Code Injection
Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
How It Works
Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization. Unlike command injection (which targets the OS shell), code injection exploits the application's own scripting engine—Python's eval(), PHP's eval(), JavaScript's eval(), Ruby's instance_eval(), or similar dynamic execution functions. The attacker crafts input that, when interpreted, executes arbitrary code within the application's runtime context.
Common attack vectors include server-side template engines where user input reaches expression evaluators, configuration files that are dynamically loaded and executed, code validators that ironically execute the code they're supposed to check, and endpoints that process serialized objects or callable definitions. In Python applications, decorators evaluated at class definition time present particularly dangerous targets since they execute before any runtime validation occurs.
The exploitation chain typically begins with identifying an endpoint that processes structured input—API parameters, file uploads, configuration snippets. The attacker then crafts payloads that break out of intended data contexts into executable code contexts. For instance, injecting @os.system('whoami') as a decorator definition, or embedding {{ ''.__class__.__mro__[1].__subclasses__() }} in template syntax to access Python internals and escalate to operating system commands.
Impact
- Complete server compromise — execute arbitrary Python, PHP, Ruby, or JavaScript code with application privileges
- Operating system command execution — break out from language runtime to system shell via subprocess calls
- Data exfiltration — read database credentials, environment variables, source code, and business data
- Persistence establishment — modify application files, inject backdoors, create scheduled tasks
- Lateral movement — leverage server access to attack internal network resources and connected services
Real-World Examples
A critical vulnerability in Langflow, a popular AI workflow framework with over 50,000 GitHub stars, exposed an unauthenticated /api/v1/validate/code endpoint meant to check Python code safety. Attackers discovered they could inject malicious decorators into class definitions. Since Python evaluates decorators at class definition time-before the AST validation logic even ran-the payload executed immediately when passed to exec(). This provided complete remote code execution without authentication.
Web template engines frequently suffer from code injection when developers allow user content in template expressions. An attacker might inject {{7*7}} to test for evaluation, then escalate to {{config.items()}} to dump Flask configuration, ultimately reaching {{''.__class__.__bases__[0].__subclasses__()}} to navigate Python's object hierarchy and invoke system commands.
Configuration management systems that dynamically import or evaluate user-supplied configuration have enabled attackers to inject executable code disguised as YAML anchors, JSON with embedded expressions, or INI files with interpreted sections.
Mitigation
- Eliminate dynamic code execution — refactor to use data-driven approaches instead of
eval(),exec(),Function(), or similar constructs - Abstract Syntax Tree (AST) allowlisting — if code execution is unavoidable, parse input into AST and validate against a strict allowlist of permitted operations before execution
- Sandboxed execution environments — use restricted interpreters (Python's RestrictedPython), containers, or separate processes with minimal privileges
- Remove or authenticate debug/validation endpoints — code validators and test endpoints are prime targets
- Input type enforcement — accept only serialized data formats (JSON, Protocol Buffers) that cannot contain executable code
- Defense in depth — run application with minimal OS privileges, use network segmentation, monitor for unusual subprocess creation

LDAP injection in Yamcs LdapAuthModule (yamcs-core < 5.12.7) enables horizontal privilege escalation for authenticated low-privilege users. By submitting a wildcard character as the username alongside a single known valid LDAP password, an attacker causes the unescaped LDAP search filter to match the first user returned by the directory query, effectively authenticating as that account. A proof-of-concept exploit is publicly available in the GitHub advisory; no CISA KEV listing exists, but the low attack complexity and published PoC make this a credible threat for any Yamcs deployment using LDAP authentication.
Metric injection in Mojolicious::Plugin::Statsd through version 0.04 for Perl allows remote unauthenticated attackers to inject arbitrary statsd metrics by supplying crafted values containing newlines, colons, or pipe characters - the delimiters of the statsd wire protocol. Applications that pass untrusted input directly into metric names or set values are affected. No public exploit exists and EPSS is 0.01% (1st percentile), placing this firmly in the low-priority tier despite network accessibility; exploitation requires attacker-controlled data to flow into metric collection paths.
Code injection in ThingsBoard 4.3.1.0 and 4.3.1.1 allows remote attackers to embed control characters and shell metacharacters into server-generated Docker Compose YAML files and MQTT publish commands via the /api/v1/provision endpoint's getGatewayDockerComposeFile and getMqttPublishCommand functions. Device credential fields - including clientId, userName, password, and credentialsId - are passed unsanitized into YAML and shell command construction, enabling injection of shell special characters such as $, backtick, and double-quote. No public exploit has been identified at time of analysis; SSVC rates exploitation as none and EPSS is 0.04%, though the RCE tag warrants scrutiny given the CVSS 4.0 score of only 2.3.
Content injection into SAP Gateway error messages exposes internal implementation details - specifically regex patterns and URI parsing logic - to authenticated remote attackers. Affecting SAP Gateway versions 750 through 758 and SAP_BASIS 795, the flaw allows an attacker with low-level network credentials to craft inputs that surface sensitive system internals via error responses. Confidentiality impact is rated low; integrity and availability are unaffected. No active exploitation is confirmed (CISA KEV absent), and EPSS sits at 0.01%, consistent with SSVC's 'exploitation: none' assessment.
CRLF injection in the hackney Erlang HTTP client library's hackney_cookie:setcookie/3 function enables HTTP response splitting against applications using versions 0.9.0 through before 4.0.1. While the function correctly validates the Name and Value cookie arguments against CRLF and control characters, it concatenates the domain and path options verbatim into the output iolist with no equivalent check, creating an injection point. An attacker who can influence the domain or path values passed to that function - for example, by submitting a crafted Host header or URL path that an application forwards directly into the cookie-setting call - can inject arbitrary additional Set-Cookie headers into the HTTP response. No public exploit identified at time of analysis per KEV absence, though SSVC confirms a proof-of-concept exists.
LDAP filter injection in Apache Airflow FAB Auth Manager (apache-airflow-providers-fab < 3.6.4) enables unauthenticated remote attackers to manipulate LDAP query logic by embedding special characters in login credentials, resulting in directory data exfiltration or authentication bypass. The vulnerability is confirmed by source code evidence: the `_search_ldap` and `_ldap_get_nested_groups` methods in `override.py` directly interpolated user-supplied input into LDAP filter strings without sanitization. No public exploit code has been identified at time of analysis and CISA KEV does not list this CVE, but the SSVC framework marks it as automatable, meaning exploitation can be scripted at scale against exposed Airflow instances using LDAP auth.
Injection vulnerability in KLiK SocialMediaWebsite 1.0 allows remote unauthenticated attackers to submit crafted HTTP POST request parameters to the application's input handler, achieving partial compromise of confidentiality, integrity, and availability. Classified under CWE-74 and tagged as Code Injection, the flaw carries a CVSS 4.0 score of 5.5 (Medium) with confirmed proof-of-concept exploit code publicly available (E:P). Despite the POC, EPSS places exploitation probability at 0.04% (14th percentile), indicating low observed real-world exploitation activity and a narrow effective target base.
Injection via HTTP GET request parameter manipulation in KLiK SocialMediaWebsite 1.0 allows remote attackers to inject arbitrary content or code through the application's parameter handler, contingent on passive user interaction. The vulnerability carries a CVSS 4.0 base score of 2.1, reflecting limited confidentiality, integrity, and availability impact scoped exclusively to the vulnerable system with no lateral impact. Publicly available exploit code exists per the E:P exploit maturity metric and SSVC poc classification, though EPSS at 0.04% (13th percentile) and the non-KEV status indicate no observed widespread exploitation.
Code injection in NousResearch hermes-agent 2026.4.23 allows remote unauthenticated attackers to inject and execute arbitrary code through the _scan_context_content function in agent/prompt_builder.py. The vulnerability has publicly available exploit code and affects all versions up to 2026.4.23, with the vendor failing to respond to disclosure attempts.
Dolibarr ERP CRM 7.0.3 contains a remote code evaluation vulnerability that allows unauthenticated attackers to execute arbitrary code by injecting PHP code through the db_name parameter. Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
Remote code injection in vps-inventory-monitoring allows authenticated attackers to execute arbitrary PHP code through the VpsTest console command. The vulnerability exists in the eval() function within VpsTest.php, exploitable by manipulating the 'vf' parameter with low attack complexity. Publicly available exploit code exists (GitHub POC published), and the maintainer has not responded to early disclosure attempts. CVSS 6.3 reflects moderate impact across confidentiality, integrity, and availability, with EPSS data unavailable but risk elevated by confirmed POC and unresponsive vendor.
Spreadsheet formula injection in Best Practical Request Tracker (RT) allows a low-privileged authenticated attacker to embed malicious formulas in ticket fields that execute when an administrator or staff member exports data to CSV and opens the file in a spreadsheet application. Affected versions span the entire RT 5.0 line prior to 5.0.10 and RT 6.0.0 through 6.0.2. No public exploit code has been identified at time of analysis and no CISA KEV listing exists, but the attack surface is broad given that CSV exports are a routine administrative workflow in ticketing systems.
Catalog zone transfer failure in PowerDNS Authoritative can be triggered by a high-privileged remote attacker who injects insufficiently validated member zone data, causing the catalog zone transfer mechanism to abort and preventing secondary nameservers from receiving zone updates. The impact is a targeted denial-of-service against DNS zone replication infrastructure, affecting any deployment using catalog zones (RFC 9432). No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV.
LDAP filter injection in Netatalk 2.1.0 through 4.4.2 enables an authenticated remote attacker to manipulate LDAP query logic, potentially reading or modifying directory entries beyond their authorization scope. The CVSS score of 4.2 (Medium) reflects real but bounded impact - high attack complexity and a requirement for low-privilege authentication constrain opportunistic exploitation. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
DNS cache poisoning in NLnet Labs Unbound 1.25.0 and earlier allows an adjacent-network attacker to inject malicious resource records into the resolver's cache by exploiting insufficient validation of authority-section RRSets. By attaching forged non-NS RRSets (such as MX records) with accompanying address records in spoofed or fragmented DNS replies, an attacker can trick Unbound into caching poisoned entries when the authority RRSet carries sufficient trust as in-zone delegation data. Publicly available proof-of-concept exploit code exists (CVSS 4.0 E:P); this is a complement fix to CVE-2025-11411, meaning systems that patched the prior vulnerability but have not upgraded to 1.25.1 remain exposed.
Object injection in Drupal Core across branches 8.0.0 through 11.3.x allows a network-accessible, highly privileged authenticated user to manipulate dynamically-determined object attributes, with potential full compromise of confidentiality, integrity, and availability. The CVSS vector (AV:N/AC:H/PR:H) confirms this is a network-reachable flaw but imposes steep prerequisites: administrator-level access and high attack complexity. No public exploit code or confirmed active exploitation has been identified at time of analysis.
Code injection in Apache OFBiz's email services exposes all versions before 24.09.06 to unauthenticated remote exploitation via CWE-94. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms no authentication or special configuration is required, and SSVC classifies the attack as automatable - meaning it can be scripted at scale. Despite the RCE tag attached by intelligence sources, CVSS impact metrics are capped at C:L/I:L/A:N and EPSS sits at 0.03% (8th percentile), indicating no public exploitation observed at time of analysis and no CISA KEV listing.
Expression Language Injection in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to inject and evaluate EL expressions through unsanitized application inputs, yielding partial confidentiality and integrity impact on the affected system. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation is network-reachable with no authentication or user interaction, and SSVC classifies the attack as automatable - a meaningful signal given OFBiz's historical exposure to EL-class vulnerabilities. However, real-world urgency is moderated by a very low EPSS score (0.03%, 8th percentile), no public exploit code identified, and no active exploitation reported; vendor patch 24.09.06 is available.
Arbitrary code execution in Alibaba ModelScope 1.25.0 allows attackers to run attacker-controlled Python by publishing or supplying a malicious model repository whose configuration file (dey_mini.yaml) names a hostile module under the ['nnet']['module'] key, which the library imports/executes when a victim loads the model (notably via the linear AEC audio pipeline). This is a classic 'trust_remote_code' code-injection flaw (CWE-94): the framework executed repo-supplied module paths without requiring the user to opt into trusting remote code. Publicly available exploit code exists (independent disclosure write-up and vendor issue/PR), but there is no public evidence of active exploitation; EPSS is very low at 0.03% (8th percentile).
CouchDB reduce injection in Budibase's V1 Views API (POST /api/views) allows authenticated Builder-role users to embed arbitrary JavaScript into CouchDB design document reduce functions via the unsanitized `calculation` parameter, resulting in code execution within CouchDB's SpiderMonkey sandbox on every subsequent view query. Affected versions are all releases of @budibase/server prior to 3.38.1, confirmed by GHSA-363w-hvwh-w7m6. No public exploit has been identified at time of analysis, and no CISA KEV listing exists, though the advisory includes detailed reproduction steps that substantially lower the exploitation barrier for users who already hold Builder privileges.
ACL Analytics versions 11.x through 13.0.0.579 contain an arbitrary code execution vulnerability that allows attackers to execute arbitrary commands by leveraging the EXECUTE function. Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
python jsonpickle 2.0.0 contains a remote code execution vulnerability that allows attackers to execute arbitrary Python commands by deserializing malicious JSON payloads containing py/repr objects. Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Metric injection in Net::Statsd::Lite (Perl) affects all releases before v0.9.0, allowing unauthenticated remote attackers to inject arbitrary statsd metrics by embedding newline, colon, or pipe characters into metric names derived from untrusted input. Because the statsd wire protocol uses these characters as record separators and field delimiters, an unsanitized metric name can smuggle additional forged metrics into the UDP stream transmitted to a statsd daemon, corrupting monitoring and telemetry data. No public exploit code exists at time of analysis and the EPSS score of 0.01% (1st percentile) indicates negligible observed exploitation activity; however, the patch diff makes exploitation trivially constructible by any attacker who can influence metric name values in a vulnerable application.
Schlix CMS 2.2.6-6 contains a remote code execution vulnerability that allows authenticated attackers to execute arbitrary PHP code by uploading malicious extension packages through the block. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
Terminal escape sequence injection in GitHub CLI 1.6.0 through 2.91.x allows authenticated attackers with pull request creation rights to inject malicious terminal control sequences into Actions workflow logs. When victims execute 'gh run view --log' or 'gh run view --log-failed' to inspect workflow runs, unsanitized escape sequences replay in their terminal, enabling window title manipulation, on-screen content alteration, or arbitrary command execution in vulnerable emulators like GNU screen. The attack requires low complexity and user interaction (victim must view logs), with impact limited to terminal integrity. CVSS score of 3.5 reflects low-severity integrity impact, though real-world risk varies significantly by terminal emulator capabilities. No active exploitation confirmed at time of analysis.
Remote attackers can execute arbitrary code on Oinone Pamirs 7.0.0 servers by sending malicious script expressions to the ScriptRunner.run() method, which evaluates untrusted input without sandboxing. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms this is remotely exploitable without authentication against default configurations. No public exploit identified at time of analysis, but SSVC marks this as automatable with partial technical impact. EPSS data unavailable. The vulnerability enables both information disclosure (C:L) and integrity compromise (I:L) according to CVSS, creating a pathway for initial access and potential privilege escalation.
Authenticated remote code execution in ORSEE 3.1.0 allows low-privileged users to execute arbitrary PHP code on the server by submitting participant profile field values prefixed with 'func:', which are passed unsanitized into eval() calls within tagsets/participant.php and tagsets/options.php. Only version 3.1.0 is confirmed affected; ORSEE is a niche academic tool used in economic research labs, limiting broad attack surface but making unpatched deployments attractive targets for insider threat or compromised-credential scenarios. No public exploit identified at time of analysis beyond a published proof-of-concept writeup on Medium, and EPSS sits at 0.06% (18th percentile), reflecting the narrow deployment footprint.
Script injection in Google Chrome's SanitizerAPI on Android (versions prior to 148.0.7778.168) enables Universal Cross-Site Scripting (UXSS), allowing unauthenticated remote attackers to bypass same-origin policy protections via a crafted HTML page when visited by a victim. The Sanitizer API - ironically a defensive web platform feature designed to strip dangerous markup - contains a code injection flaw that permits injected scripts or HTML to survive sanitization. No active exploitation has been confirmed (not in CISA KEV), EPSS stands at 0.03% (7th percentile), and SSVC classifies exploitation as none; however, the UXSS impact class warrants prompt patching given Chrome's ubiquitous deployment footprint.
Remote code inclusion in Yordam Library Automation System versions 19.5 through 22.0 allows unauthenticated attackers to execute arbitrary code with high integrity and confidentiality impact via user interaction. The vulnerability was reported by Turkey's National Cyber Security Directorate (USOM), indicating potential targeting of Turkish government or educational institutions using this library management software. With network-accessible attack vector and low complexity (CVSS AV:N/AC:L), this represents a significant risk to organizations running unpatched versions despite requiring user interaction (UI:R).
Remote code execution in Archon 0.1.0 enables attackers to execute arbitrary commands and steal API keys when victims access a malicious HTML page. The attack exploits insufficient input validation (CWE-94) to control the Archon UI, run prompts on behalf of authenticated users, and exfiltrate all information displayed in the interface. With EPSS score of 0.04% (13th percentile) and no confirmed active exploitation, this represents a web-to-client attack requiring social engineering but offering significant post-exploitation capabilities once triggered.
HTML and JavaScript injection via email notifications in GitLab CE/EE (versions 15.11 through 18.11.2) allows an authenticated low-privileged user to deliver malicious content to other users' inboxes by embedding unsanitized markup into platform-generated notifications. The attack crosses a scope boundary (S:C in CVSS) because the injected code executes in the recipient's email client or browser context rather than GitLab itself, enabling phishing, credential harvesting, or session theft against targeted users. No public exploit has been identified at time of analysis and SSVC signals no active exploitation, though the broad version range - spanning over three years of releases - expands the exposed population significantly.
Content injection in Palo Alto Networks Broker VM 30.0 (versions prior to 30.0.24) allows an authenticated administrator with local access to inject arbitrary content into certain administrative fields within the appliance. The vulnerability carries a CVSS 4.0 score of 1.1, reflecting its highly constrained exploitation prerequisites: local access, low-privilege authentication, and limited integrity impact with no confidentiality or availability consequences. No public exploit identified at time of analysis, and SSVC assessment confirms no observed exploitation, making this a low-urgency finding for most organizations.
Command injection in TeamViewer DEX Platform On-Premises (formerly 1E DEX Platform On-Premises) prior to version 9.2 allows authenticated low-privileged users to execute elevated commands on endpoints managed by the platform. The vulnerability stems from improper input validation (CWE-20) within specific platform instructions, enabling a user holding only 'questioner' privileges to escalate their effective impact to arbitrary command execution on connected devices. No public exploit exists and EPSS is low (0.08%), though SSVC rates Technical Impact as 'total', reflecting the downstream risk to managed endpoints despite the bounded CVSS partial-impact scores.
NGINX Open Source configured to proxy HTTP/2 traffic with proxy_http_version set to 2 combined with proxy_set_body allows remote unauthenticated attackers to inject frame headers and payload bytes to upstream peers, enabling potential header injection or request manipulation attacks. The vulnerability affects default configurations without requiring authentication or user interaction, with CVSS 5.8 indicating moderate integrity impact across networked systems. No public exploit code or active exploitation has been confirmed at this time.
Arbitrary shortcode execution in the Advanced Custom Fields: Extended WordPress plugin (all versions through 0.9.2.3) enables unauthenticated remote attackers to invoke any shortcode registered in a WordPress installation by submitting crafted input to exposed front-end forms. The flaw exists in two code paths - the form front-end renderer and the email action handler - both of which pass user-controlled values directly to WordPress's do_shortcode() function without validation or allowlisting. No active exploitation has been identified (SSVC: Exploitation none, not in CISA KEV), and EPSS sits at 0.09% (25th percentile), though the attack is flagged as automatable, raising the potential for opportunistic scanning at scale.
CRLF injection in SUBNET Solutions' PowerSYSTEM Center email notification service enables adjacent-network, low-privilege attackers to manipulate SMTP protocol sequences during SMTPS communication. All three major release lines are affected: 2020 (≤5.28.x), 2024 (6.0.x-6.1.x), and 2026 (7.0.x), as confirmed by CISA ICS-CERT advisory ICSA-26-132-02. No public exploit or active exploitation has been identified; EPSS is 0.01% and SSVC classifies exploitation as none, placing this firmly in a low-urgency remediation tier for most organizations.
Argument injection in Fortinet FortiDeceptor 5.0 through 6.0.2 allows authenticated administrators with read-only permissions to read arbitrary log files via crafted HTTP requests, exposing sensitive system and audit logs. The vulnerability requires valid admin credentials but no elevated privileges, making it accessible to lower-privileged authenticated users. No public exploit code or active exploitation has been confirmed at time of analysis.
Code injection in SAP Application Server ABAP for SAP NetWeaver and ABAP Platform allows authenticated attackers to execute arbitrary code for subscribed channel users by sending specially crafted inputs. The vulnerability has low integrity impact with no confidentiality or availability consequences. CVSS 4.3 (low severity) reflects the requirement for authenticated access, but the ability to affect other users elevates practical risk in multi-tenant environments.
Remote code execution in Kubectl MCP Server v1.1.1 allows unauthenticated network attackers to execute arbitrary commands on systems running the vulnerable server through crafted HTML-based exploitation vectors. Despite a critical 9.8 CVSS score, EPSS rates exploitation likelihood at only 0.02% (4th percentile), suggesting limited real-world targeting thus far. The vulnerability is classified as CWE-94 (Code Injection), affecting an open-source Model Context Protocol (MCP) server implementation for Kubernetes management. No CISA KEV listing indicates absence of confirmed widespread exploitation at time of analysis.
HTTP::Tiny versions before 0.093 for Perl fail to validate carriage return and line feed (CRLF) characters in HTTP request lines and header values, allowing attackers who control input URLs or headers to inject additional HTTP headers and smuggle requests to upstream servers. Remote unauthenticated attackers can exploit this via crafted URLs passed to webhook or URL fetch endpoints, achieving limited information disclosure and integrity compromise. EPSS score of 0.03% (percentile 7%) indicates low practical exploitation probability despite network-vector accessibility.
CSS scoping bypass in Mermaid's default configuration allows injected styles to escape the diagram SVG container and apply globally to the host page via the `fontFamily`, `themeCSS`, and `altFontFamily` initialization options. Affected are npm/mermaid versions up to 10.9.5 and 11.0.0-alpha.1 through 11.14.0 when rendered with default settings - covering any web application that renders user-supplied diagram definitions, such as wikis and documentation platforms. An attacker who can influence diagram initialization parameters can achieve page defacement and DOM attribute exfiltration via CSS `:has()` selectors; a public proof-of-concept demo exists on mermaid.live, though no CISA KEV listing or widespread exploitation is recorded, and the EPSS of 0.05% (15th percentile) confirms low current exploitation activity.
HTML injection in Mermaid's state diagram `classDef` parser allows escape from the SVG rendering context into the parent document DOM, affecting npm/mermaid through v11.14.0 and through v10.9.5 under the default `securityLevel` configuration. By embedding SVG/style-closing sequences inside CSS property values, an attacker can inject arbitrary HTML and CSS that overlays the full browser viewport - enabling UI redressing and phishing-style attacks on any platform that renders user-supplied diagrams. A public proof-of-concept is available per SSVC assessment; however, `<script>` tag stripping is confirmed to prevent classic XSS, and no CISA KEV active exploitation has been recorded.
CSS injection in Mermaid's diagram rendering engine (npm/mermaid v11.14.0 and earlier, v10.9.5 and earlier) allows attackers who can supply diagram input to inject arbitrary CSS rules into the host page. The flaw exists because `classDef` style strings are captured by an unrestricted Jison regex and written unsanitized to `style.innerHTML`, enabling page defacement, user tracking via CSS `url()` callbacks, and DOM attribute exfiltration via CSS `:has()` selectors. A public proof-of-concept with a live demo is confirmed in the GHSA advisory; no CISA KEV listing at time of analysis.
OpenClaw before version 2026.4.20 fails to preserve untrusted labels on webhook-triggered cron agent output, allowing events to be recorded as trusted system events instead of untrusted events. This trust-labeling issue can strengthen prompt-injection attacks by rendering attacker-controlled webhook data as legitimate system events, though it does not directly bypass authentication, tool policy, or sandboxing controls.
OpenClaw versions 2026.4.5 through 2026.4.19 allow local attackers with user privileges to redirect credentialed MiniMax API requests to attacker-controlled servers via environment variable injection in workspace dotenv files, exposing MiniMax API keys in Authorization headers. The vulnerability requires user interaction (opening a malicious workspace) and local access but achieves high confidentiality impact by exfiltrating sensitive API credentials.
GuardDog versions 2.6.0 through 2.9.0 fail to escape terminal control characters in human-readable scan output, allowing malicious packages to inject ANSI or OSC escape sequences that can clear analyst terminals, rewrite CI logs, or inject spoofed content. The vulnerability affects file paths, code snippets, and messages parsed from package content and rendered directly to stdout without sanitization. Remote attackers can exploit this by distributing packages with specially crafted filenames or source code containing escape sequences, and requires only user interaction (running the scanner on the malicious package).
Insecure deserialization in CosyVoice's model loading pipeline permits arbitrary code execution on any system that loads a maliciously crafted model directory via the Web UI. The framework invokes torch.load() on model weight files (llm.pt, flow.pt, hift.pt) without the weights_only=True safety parameter, allowing Python's pickle module to deserialize and execute arbitrary objects embedded in those files. An attacker who can persuade a victim to point the CosyVoice Web UI at an attacker-controlled model directory - whether via a trojanized download, a shared malicious repository, or direct filesystem access - achieves code execution on the victim's machine at the moment of model loading. No public exploit code or CISA KEV listing is recorded at time of analysis; EPSS is 0.02% (5th percentile) and SSVC assesses exploitation as none, consistent with the social-engineering precondition required.

Hex-Rays IDA Pro 9.2 and 9.3 before 9.3sp2 allows local code injection through argument injection in Clang dependency-file generation, enabling attackers to place malicious code into the plugins directory when a victim opens an attacker-supplied .i64 file. The vulnerability requires local access and user interaction (opening a malicious file) but grants high integrity and confidentiality impact. No public exploit code or CISA KEV status has been confirmed at the time of analysis.
Code injection in codelibs Fess up to 15.5.1 allows remote attackers with high privileges to execute arbitrary code via manipulation of the content argument in the AdminDesignAction.java JSP file handler. Publicly available exploit code exists for this vulnerability, and the vendor has not responded to early disclosure notification.
CSS declaration injection in Hono's JSX server-side renderer allows remote attackers to inject arbitrary CSS declarations via untrusted `style` object values or property names, enabling visual manipulation, outbound CSS requests to attacker hosts, and UI hijacking. Affects Hono versions before 4.12.18 when rendering JSX server-side with user-controlled style object inputs. No JavaScript execution or HTML breakout possible; impact limited to CSS scope.
SQL and CQL injection vulnerability in PraisonAI multi-agent teams system versions 2.4.1 through 4.6.33 allows authenticated attackers to execute arbitrary SQL or CQL commands by injecting malicious collection names into knowledge-store implementations. The vulnerability affects applications that pass untrusted collection names to optional SQL/CQL-backed storage backends, enabling data exfiltration, modification, or deletion with low complexity exploitation.
Memory access violations occur in Linux kernel on Xilinx ZynqMP systems when OP-TEE device tree nodes are manually defined, preventing U-Boot's OP-TEE injection logic from properly inserting reserved-memory nodes. This affects Linux kernel versions 6.9 through 7.0 on ARM64 ZynqMP platforms, allowing local authenticated users to cause denial of service through runtime memory access faults. Vendor-released patches are available across multiple stable branches (6.12.75, 6.18.16, 6.19.6, 7.0).
Code injection in 1C-Bitrix (Bitrix Site Manager) through 25.100.500 lets an actor holding SOURCE/WRITE permissions on the Translate Module upload a PHP file together with a .htaccess file and have it executed by the web server, yielding arbitrary code execution on the host. Publicly available exploit code exists (karmainsecurity PoC), but there is no public exploit identified as actively used in attacks, and EPSS is very low at 0.02%. Notably, the vendor disputes this as a vulnerability, calling it intended behavior for high-privileged users who legitimately upload translated pages.
A SSTI (server side template injection) vulnerability in the custom template export function in yeti-platform yeti before 2.1.12 allows attackers to execute code on the application server. Rated high severity (CVSS 7.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Remote code execution in FacturaScripts through authenticated file upload allows attackers with valid credentials to bypass MIME type validation by prepending GIF89a magic bytes to PHP files, resulting in executable files stored in a web-accessible directory. An attacker can upload a malicious PHP file disguised as a GIF image via the product image upload functionality, then directly execute arbitrary commands on the server. The vulnerability affects versions 2025.81 and earlier; publicly available proof-of-concept code exists demonstrating end-to-end exploitation.
Remote code execution in Hitachi Virtual Storage Platform G, F, E, and One Block series allows unauthenticated network attackers to execute arbitrary code on storage controllers and maintenance consoles with low impact across confidentiality, integrity, and availability due to changed scope (CVSS 8.3, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C). The vulnerability affects the Storage Navigator interface and maintenance console across multiple VSP product lines spanning enterprise and mid-range storage arrays. EPSS data not available; no evidence of active exploitation or public POC at time of analysis. Vendor-released patches available with specific firmware versions required for each product family.
CSS Parser gem disables HTTPS certificate validation by setting OpenSSL::SSL::VERIFY_NONE, allowing man-in-the-middle attackers to inject or modify CSS content loaded via HTTPS. Any application using CSS Parser versions prior to 2.1.0 to fetch external stylesheets over HTTPS can be exploited by network-positioned attackers without authentication. A proof-of-concept using mitmproxy or Burp Suite demonstrates practical exploitation; CVSS 5.8 reflects the network attack vector and integrity impact, but real-world risk depends on whether the application loads stylesheets from untrusted or attacker-controllable URLs and whether the attacker can intercept network traffic.
Code injection in the Node.js npm package next-npm-version 1.0.1 (published by afeiship/@jswork) allows attacker-controlled input to be passed into a shell execution context, achieving arbitrary command execution (CWE-94). A proof-of-concept exists in a public gist, though there is no evidence of active exploitation; the EPSS probability is very low (0.03%, 10th percentile) and CISA SSVC rates exploitation as 'none' but automatable with total technical impact. The NVD CVSS of 9.8 (AV:N) appears optimistic for a version-bumping developer utility whose command execution is far more plausibly reached via local/library invocation than remote network access.
Script injection in Google Chrome's UI layer prior to version 148.0.7778.96 enables Universal Cross-Site Scripting (UXSS), allowing a remote attacker to inject arbitrary scripts or HTML into the browser's execution context. Successful exploitation requires social engineering the victim into performing specific UI gestures while visiting a crafted HTML page. No public exploit has been identified at time of analysis, EPSS sits at 0.01% (1st percentile), and CISA's SSVC framework classifies exploitation status as none with no automatable attack path.
Unvalidated Omnibox input in Google Chrome prior to version 148.0.7778.96 enables remote attackers to inject arbitrary scripts and HTML (universal XSS) via malicious network traffic, affecting users who click on crafted links. The vulnerability requires user interaction but crosses security boundaries due to its scope impact. No active exploitation has been publicly confirmed, though a patch is available from Google.
Insufficient input validation in Google Chrome on Android prior to version 148.0.7778.96 allows local attackers to inject arbitrary scripts or HTML via a crafted Chrome Extension, leading to Universal Cross-Site Scripting (UXSS). The vulnerability requires user interaction and local system access but poses a medium risk due to its ability to bypass same-origin policy protections within the browser context. No public exploit has been identified at the time of analysis.
Denial of service in Linux kernel KVM x86 nested virtualization allows local privileged attackers to crash virtual machines by manipulating vCPU state through userspace MP_STATE and injected event stuffing. When a vCPU is awakened from a blocking state in L2 (nested guest mode) with an already-injected event, the kernel generates spurious KVM_EXIT_UNKNOWN exits that typically terminate the VM. The vulnerability stems from insufficient validation of impossible vCPU states that userspace can artificially create, despite architectural safeguards that should prevent injected events during blocking. CVSS 5.5 (local, low complexity, high availability impact); EPSS 0.02% indicates minimal widespread exploitation likelihood.
Malicious environment variable injection in Oracle Cloud Native Environment Command Line Interface v2.3.2 allows local authenticated users with low privileges to execute arbitrary code through user interaction, compromising systems running the affected CLI tool. The vulnerability requires local access and user action but results in high-impact code execution with full confidentiality and integrity compromise.
Event spoofing in sse-channel (npm) allows attackers to inject arbitrary Server-Sent Events (SSE) messages by passing unsanitized user input to the event, retry, or id fields, enabling client-side manipulation and data integrity violations. Affects sse-channel versions 4.0.0 and earlier; patched in v4.0.1. No public exploit code identified at time of analysis, but vulnerability is straightforward to exploit if user-controlled data reaches SSE field parameters.
Formula injection in Kimai 2.27.0 through 2.53.0 allows authenticated users with ROLE_USER to create tags containing formula strings (e.g., =SUM(54+51)) via the POST /api/tags endpoint. When administrators export timesheets to XLSX format, the ArrayFormatter joins tag names without sanitization, and OpenSpout automatically promotes formula-prefixed strings to FormulaCell objects. Excel or LibreOffice Calc evaluates these formulas when the exported file is opened, enabling code execution on any workstation that imports and opens the poisoned spreadsheet. Publicly available exploit code demonstrates the attack via normal user account and admin export workflow.
XML injection in Traccar 6.11.1 through 6.12.x allows authenticated users with low privileges to inject malicious XML into KML and GPX export files by crafting device names, corrupting file structure and spoofing location data when other users open exported files. Vendor-released patch: version 6.13.0.
Traccar versions 6.11.1 through 6.13.0 fail to escape user-controlled device and computed attributes in CSV export functionality, allowing authenticated attackers to inject spreadsheet formulas that execute when a manager or administrator opens the exported file, potentially leading to command execution or data exfiltration. The vulnerability requires user interaction (opening the CSV) but affects all confidentiality, integrity, and availability once exploitation occurs. Patch available in version 6.13.0.
Frappe Framework ERPNext 13.4.0 contains a sandbox escape vulnerability in RestrictedPython that allows authenticated users with System Manager role to execute arbitrary code by exploiting frame. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
Prototype pollution in EvoMap Evolver versions prior to 1.69.3 allows local attackers with high privileges to inject malicious properties into Object.prototype via unfiltered Object.assign() calls in the mailbox store module, potentially modifying the behavior of all JavaScript objects and causing information disclosure or denial of service. The vulnerability requires file system write access to the messages.jsonl persistence file and high privileges, limiting real-world exploitability to insider or local compromise scenarios.
Argument injection in Prefect up to 3.6.25.dev6 allows authenticated attackers to execute arbitrary git commands via specially crafted commit_sha or directories parameters in the GitRepository Pull Handler (src/prefect/runner/storage.py). An attacker can inject git flags like --upload-pack or --config to achieve remote code execution with the privileges of the Prefect runner process. Publicly available exploit code exists, and the vendor has released a patched version (3.6.25.dev7) that validates commit SHA format and adds command-line argument separators to block injection.
Code injection via Websocket API in AV Stumpfl Pixera Two Media Server ≤25.2 R2 allows unauthenticated remote attackers to execute arbitrary code with low complexity. Publicly available exploit code (GitHub Gist) enables network-based compromise with partial impact to confidentiality, integrity, and availability (CVSS:3.1/C:L/I:L/A:L). Vendor-released patch version 25.2 R3 addresses the vulnerability. Despite network vector and proof-of-concept availability, no CISA KEV listing or EPSS data indicates limited observed exploitation at time of analysis.
Code injection via the eval function in Langflow's LambdaFilterComponent allows remote authenticated attackers to execute arbitrary code with low-to-medium integrity and confidentiality impact. The vulnerability affects Langflow up to version 1.8.4, requires user login (PR:L), and has publicly available exploit code. The vendor did not respond to early disclosure notification.
Code injection vulnerability in nextlevelbuilder ui-ux-pro-max-skill up to 2.5.0 allows authenticated remote attackers to execute arbitrary code via unsanitized plugin names in the Tailwind Config Generator. The _format_plugins function constructs require() statements without validation, enabling attackers with login credentials to inject malicious JavaScript into the Tailwind configuration. Publicly available exploit code exists and the vendor has released a patch via pull request, though adoption status is unconfirmed.
Linux kernel GSO feature check reads uninitialized IPv4 header data when processing packets from PF_PACKET paths, causing kernel memory disclosure or denial of service. The vulnerability affects multiple kernel versions before 6.12.81, 6.19.12, and 7.0, and requires local user access to trigger via raw packet injection.
Code injection in ExifTool versions up to 13.53 allows local attackers with limited privileges to execute arbitrary code via manipulation of the -ee argument in the Process_mrld function when processing JPEG/QuickTime/MOV/MP4 files. The vulnerability has a very low CVSS score of 1.9 due to local-only attack vector and low impact, but is tagged as RCE. Vendor-released patch available in version 13.54.
Code injection in Bootstrap CMS 0.9.0-alpha page creation handler allows authenticated remote attackers to inject arbitrary code via the body parameter in resources/views/pages/show.blade.php, with publicly available exploit code and a CVSS score of 2.1 reflecting low confidentiality/integrity impact. The vulnerability affects an unmaintained product with an inactive code repository, limiting real-world exposure but enabling opportunistic exploitation of legacy deployments.
Code injection in Qt SVG module allows attackers to execute arbitrary QML/JavaScript when applications load malicious SVG files through Qt Quick's VectorImage component. Exploitation requires local file access and user interaction (opening crafted SVG). While QML execution is more restricted than native code, attackers can still trigger denial of service, exfiltrate application data, or manipulate UI logic depending on the victim application's privilege context. No active exploitation confirmed (not in CISA KEV), but patch available from Qt Project reduces urgency for immediate emergency response.
SQL injection in n8n's Oracle Database node allows attackers to inject arbitrary SQL commands through the Limit field when user-controlled input is passed via expressions, enabling data exfiltration from connected Oracle databases. Exploitation requires a specific workflow configuration where external input (e.g., from webhooks) reaches the Limit field; authentication depends on the webhook's access controls. The vulnerability affects n8n versions prior to 1.123.32, 2.17.4, and 2.18.1, and vendor-released patches are available.
Code injection in EyouCMS versions 1.7.0 through 1.7.9 allows authenticated administrators to execute arbitrary PHP code via the Template File Handler's editFile function in FilemanagerLogic.php, enabling remote code execution on the underlying server. All versions across the entire 1.7.x branch are affected, and a proof-of-concept exploit is publicly available on Gitee. This vulnerability is not listed in CISA KEV; EPSS at 0.04% and SSVC automatable:no reflect the high-privilege prerequisite that limits mass exploitation, though the public POC lowers the bar for targeted insider or credential-compromise attacks.
KDE KCoreAddons before version 6.25 contains an improper neutralization of special elements vulnerability in the KShell::quoteArgs() function that fails to safely escape metacharacters and control characters, allowing local attackers with user interaction to inject arbitrary shell commands or terminal control sequences when user input is passed to shell execution contexts. Applications using this method to quote arguments for security-critical operations are affected; exploitation requires local access and user interaction but can achieve arbitrary code execution with user privileges.
Cypher injection in LogonTracer prior to v2.0.0 allows remote attackers to alter database contents by submitting specially crafted Windows event log data. The vulnerability requires user interaction to load the malicious log data but results in integrity compromise of the underlying database due to improper input sanitization in Cypher query construction.
SpEL expression injection in baomidou dynamic-datasource 2.5.0 allows authenticated remote attackers to execute arbitrary code via the DsSpelExpressionProcessor component. The vulnerability stems from unsafe evaluation of Spring Expression Language (SpEL) in datasource routing logic, enabling attackers with application access to inject malicious expressions that execute with application privileges. No public exploit code or active exploitation has been identified at time of analysis, though upstream fix is available.
Code injection in Envoy up to 1.33.0 via improper query parameter handling in the Header Mutation filter allows authenticated remote attackers to inject arbitrary code through the params.add function, resulting in limited confidentiality and integrity impact. The CVSS 5.3 score reflects the requirement for prior authentication and limited scope of impact, though the injection vector in a core HTTP filtering component warrants prompt patching.
STARTTLS response injection in MailKit prior to version 4.16.0 allows man-in-the-middle attackers to downgrade SASL authentication mechanisms by injecting malicious protocol responses before TLS negotiation completes. The vulnerability stems from failure to flush the internal read buffer when upgrading from plaintext to encrypted connections, enabling attackers to force weaker authentication (e.g., PLAIN instead of SCRAM-SHA-256) on affected SMTP, IMAP, and POP3 connections. User interaction is required (establishing a mail connection through the client), and exploitation requires network position to intercept and modify STARTTLS exchanges. Vendor-released patch version 4.16.0 addresses the issue.
XML injection in Kirby CMS's XML creator toolkit allows attackers who can supply input to `Xml::value()`, `Xml::tag()`, `Xml::create()`, or the `Xml` data handler to bypass CDATA escaping and inject arbitrary XML structure into generated output. Affected versions are getkirby/cms below 4.9.0 and 5.0.0 through 5.4.0 exclusively when site or plugin code passes attacker-controlled data through these methods. No public exploit has been identified at time of analysis, EPSS is 0.04%, and CISA SSVC rates exploitation as none — real-world risk is conditional on a specific non-default usage pattern not present in the Kirby core.
Server-Side Request Forgery (SSRF) in ntfy (ntfy.sh) before v2.22.0 allows authenticated remote attackers to make the server issue arbitrary HTTP requests to internal network resources by exploiting an unanchored regex pattern in the web push endpoint allow-list. Despite the CVE description attributing the vulnerability to the 'parseActions' function with an RCE classification, the confirmed fix in v2.22.0 - tightening the web push endpoint allow-list regex to prevent SSRF via unanchored pattern matching - indicates the real impact is SSRF, not arbitrary code execution. No active exploitation has been confirmed (not in CISA KEV), though a public proof-of-concept gist exists from the reporter.
