SQL injection in SourceCodester Air Cargo Management System 1.0 exposes the `/classes/Master.php?f=save_cargo_type` endpoint to database manipulation via a crafted `id` argument. Exploitation requires high-privilege authenticated access (CVSS 4.0 PR:H), constraining the realistic attacker pool to compromised or shared administrator accounts. A public proof-of-concept is available on GitHub, confirmed by VulDB reporting; no patch has been identified at time of analysis.
Information disclosure in Webkul Bagisto up to version 2.4.4 allows authenticated admin users to extract unintended customer data by manipulating the `query` parameter at the `/admin/customers/search` endpoint. The vulnerability carries a CVSS 4.0 score of 2.0 - reflecting limited confidentiality impact (VC:L) and a high-privilege requirement (PR:H) - meaning only actors already holding admin credentials can trigger it. A public proof-of-concept exploit exists on GitHub; however, no active exploitation has been confirmed via CISA KEV, and the vendor has acknowledged the issue, stating partial remediation is already underway with remaining fixes planned for upcoming releases.
Improper access control in Webkul Bagisto's Customer Item Deletion Endpoint (versions up to 2.4.4) permits a remotely-accessible, authenticated attacker to delete customer items beyond their authorization scope. A public proof-of-concept exploit is available on GitHub, and the vendor has acknowledged the issue, confirming partial fixes have shipped with remaining remediation planned for future releases. This is not currently listed in the CISA KEV catalog, and real-world impact is moderated by the PR:H authentication requirement.
Order integrity bypass in the Epeken All Kurir for Woocommerce WordPress plugin (≤2.1.2) allows unauthenticated network attackers to mark arbitrary orders as confirmed - and, under non-default payment configurations, as paid - without owning the order or completing a real transaction. The plugin's payment-confirmation handler performs no origin check and no actual payment verification, making it possible for an adversary to fraudulently trigger fulfillment workflows. No public exploit code has been identified at time of analysis, and EPSS sits at 0.15% (4th percentile), indicating low observed exploitation probability despite the unauthenticated network vector.
Server-side request forgery in feedmob fm-mcp-servers 0.0.3 allows a locally authenticated attacker to manipulate the `downloadUrl` argument in the `downloadReport` function, causing the server to issue arbitrary outbound HTTP requests to attacker-controlled internal or external targets. Exploitation is constrained to local access only (AV:L), significantly limiting the practical attack surface, though a public proof-of-concept is available via GitHub issue #198. No vendor patch exists; the vendor has not responded to the coordinated disclosure.
Race condition in KUNBUS piControl 2.6.2 enables a local authenticated attacker to corrupt kernel heap memory and disclose adjacent kernel memory contents by issuing concurrent crafted requests through the piControl character device. The flaw resides in the event notification subsystem, where improper synchronization between threads allows an attacker to win a timing window and manipulate shared kernel state. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis; the CVSS 4.0 score of 5.9 reflects the high-complexity, local-access nature of the attack.
Memory corruption and denial of service in Zephyr RTOS's second-generation delayable work queue (kernel/work.c) arise because the documented safe-cancellation APIs-k_work_cancel_delayable_sync() and k_work_flush_delayable()-fail to block until an in-flight timeout handler completes before returning, allowing callers to free a k_work_delayable object that work_timeout() subsequently dereferences. The race exists exclusively in SMP builds; work_timeout() performs a use-after-free read of the freed object's flags and, if the memory slot has been reused so the bail check passes, a use-after-free write to wp->flags and a submit against a stale dw->queue pointer. No public exploit has been identified and the vulnerability is absent from the CISA KEV catalog; exploitation is probabilistic and gated on kernel-mode code execution with influence over subsystem work-item teardown timing.
Path traversal in dromara lamp-cloud (versions up to 5.10.0) exposes the chunk-check endpoint of FileChunkController.java to remote directory traversal via a crafted 'Name' argument, potentially allowing attackers to read or write files outside the intended upload directory. No authentication is required per the CVSS 4.0 vector (PR:N), and a public exploit has been disclosed (CVSS E:P modifier), lowering the barrier for opportunistic exploitation. The vendor was notified via GitHub issue #413 but has not yet responded, leaving no official patch available at time of analysis.
Path traversal in Dromara lamp-cloud up to version 5.10.0 allows remote unauthenticated attackers to manipulate file storage paths via the bucket and bizType parameters in FileAnyoneController.java. The affected endpoint appears intentionally public (indicated by the 'Anyone' controller name), lowering the bar for exploitation significantly. No vendor patch is available at time of analysis, and a public proof-of-concept exploit exists, though no CISA KEV listing confirms active mass exploitation.
Unsafe Java deserialization in alldatacenter alldata up to version 0.6.8 exposes the xxl-rpc Listener to remote, unauthenticated exploitation via crafted Hessian2-serialized payloads. The Hessian2Input.readObject() function in HessianSerializer.java processes attacker-controlled input without class validation, enabling object deserialization attacks that can activate gadget chains present in the application's JVM classpath. A public proof-of-concept exploit is available, the project has formally declined to issue a patch, and all users on affected versions face a permanent unmitigated known risk.
Stack exhaustion in libdm's LVM metadata configuration parser allows any LVM command processing attacker-crafted block device metadata to crash, resulting in denial of service on affected Linux systems. The flaw is exploitable in shared storage, SAN, or virtualization environments where an adversary can supply a maliciously structured block device to a target system running LVM2. No public exploit code has been identified at time of analysis, and the vulnerability is absent from CISA KEV; however, the provided CVSS vector is materially inconsistent with the described DoS impact and warrants independent verification.
Hard-coded credentials in Dell Wyse Management Suite (WMS) versions prior to 2605.0.2 expose management-plane access to any low-privileged local user who discovers them. Exploitation yields high confidentiality and integrity impact - an attacker can read sensitive management data and alter system state - while availability is unaffected. No public exploit code or CISA KEV listing exists at time of analysis, but the CWE-798 class is historically trivial to exploit once credentials are extracted from binaries or configuration files.
Remote resource exhaustion in the TRENDnet TEW-816DRM router's bftpd FTP service allows unauthenticated remote attackers to cause a denial-of-service condition by exploiting improper handling of the USERLIMIT_GLOBAL configuration parameter in /etc/bftpd.conf. The vulnerability, classified as CWE-400 (Uncontrolled Resource Consumption), affects the end-of-life firmware GURNC4.OT182B-C-TN-R1B028-US.EN, and no vendor patch will ever be issued. Proof-of-concept exploit code is publicly available per the CVSS 4.0 E:P supplemental metric, lowering the technical bar for exploitation.
SQL injection in SourceCodester Simple Client Management System 1.0 exposes the application's database to unauthenticated remote attackers via the unsanitized `ID` parameter in `/classes/Master.php?f=save_service`. The vulnerability allows arbitrary SQL query manipulation, enabling data exfiltration and potential data modification against the backend database. A publicly disclosed proof-of-concept exploit exists (referenced in GitHub issue lyf3273/CVE/issues/3), elevating near-term exploitation risk for any internet-exposed instances despite the limited prevalence of this product.
Cross-site scripting in IBM Db2 Mirror for i 7.4, 7.5, and 7.6 enables a remote low-privileged authenticated attacker to inject and execute arbitrary scripts in a victim user's browser session via the product's web interface. The CVSS vector (I:H) indicates that successful exploitation can result in high-integrity impact - such as unauthorized administrative actions or session hijacking - when a higher-privileged user interacts with attacker-controlled content. No public exploit code and no confirmed active exploitation have been identified at the time of analysis.
JWT claim validation failures in Red Hat Quay's federated robot account and SSO authentication pathways allow an attacker who already holds a legitimately-issued token from the same configured identity provider to bypass audience (`aud`), authorized party (`azp`), and subject (`sub`) restrictions. Affected deployments include Red Hat Quay 3 and Red Hat OpenShift Update Service across all currently tracked versions. Successful exploitation yields unauthorized access to registry resources beyond the attacker's intended scope, including potential cross-account or cross-namespace read and write access within the Quay instance. No public exploit code has been identified and this CVE is not currently listed in the CISA KEV catalog.
Improper access control in Tenable Security Center enables authenticated non-administrative users to read application settings that fall outside their assigned organizational or role-based scope, constituting an unauthorized information disclosure. The vulnerability requires only a low-privileged authenticated account and is exploitable over a network with no user interaction or special triggering conditions, per the CVSS 4.0 vector (AV:N/AC:L/PR:L). No public exploit code has been identified and Tenable has published advisory TNS-2026-22; the CVSS 4.0 score of 5.3 (Medium) reflects the limited, read-only nature of the exposure.
E-Municipality by Universal Software Inc. exposes a remotely exploitable authentication bypass via trusted identifier exploitation (CWE-305), affecting all versions from 20251127 up to the patched release 20260204. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms that unauthenticated remote attackers can reach the vulnerable authentication layer with no user interaction and no access prerequisites, resulting in limited integrity compromise. Disclosed by Turkey's national CSIRT (USOM), no public exploit or CISA KEV listing exists at time of analysis.
Remote unauthenticated information disclosure in Dell Wyse Management Suite (WMS) versions prior to 2605.0.2 allows network-accessible attackers to access sensitive data through a critical management function lacking authentication enforcement. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires no credentials, no user interaction, and no special configuration - any reachable WMS instance running an unpatched version is a valid target. No public exploit code and no confirmed active exploitation (CISA KEV) have been identified at time of analysis; a vendor-released patch is available.
Authenticated users with Perm.Download=false can extract cryptographic content hashes (MD5, SHA1, SHA256, SHA512) for any file within their scope via filebrowser's /api/resources?checksum= endpoint, bypassing the intended download permission gate. The resourceGetHandler's checksum branch reads entire file content to compute digests but omits the Perm.Download check enforced by all sibling handler paths (raw, preview, subtitle). This is an incomplete remediation of CVE-2026-35606; no public exploit is identified at time of analysis, and the CVSS 4.0 vector (PR:L, VC:L) confirms exploitation requires an authenticated session. The hash oracle enables content confirmation, change detection, and offline brute-force of low-entropy files without ever receiving the file bytes directly.
Arbitrary database table row deletion in RosarioSIS up to version 12.7.4 allows authenticated users to issue DELETE statements against any table in the database by manipulating the unsanitized `table` parameter in `modules/Students/includes/Medical.inc.php`. While `DBEscapeIdentifier()` prevents classic SQL injection syntax escapes, it does not restrict which table is targeted - enabling destruction of records far beyond the medical module's intended scope, including user accounts, grades, or other critical school data. No public exploit or CISA KEV listing has been identified at time of analysis; a vendor-released patch is available in version 12.8.
Scope cap bypass in the Grav API plugin before 1.0.13 allows a holder of a scoped API key issued on a super admin account to call unauthorized DemoController operations. The private requireSuper() method exits early after confirming isSuperAdmin(), never reaching requirePermission() where api_key_scopes enforcement occurs, making the scope restriction on that key inert for the baseline() and reset() endpoints. Impact is bounded to demo-engine control - forced demo resets or baseline captures - and is conditional on demo mode being actively configured with writable resources. No public exploit is identified at time of analysis.
Cross-site request forgery in RosarioSIS up to version 12.8 allows a remote unauthenticated attacker to trigger unintended state-changing actions in Modules.php by luring an authenticated user to a malicious page. The vulnerability stems from the absence of CSRF token validation on the modfunc parameter, compounded by insufficient sanitization of modfunc= in rendered HTML/Markdown output via MarkDownHTML.fnc.php. No public exploit has been identified and the vulnerability is not listed in CISA KEV; the vendor-confirmed patch is available in v12.9.
Cross-site request forgery in the iCagenda Joomla extension (versions prior to 4.0.11) exposes multiple frontend state-changing operations - including event registration actions - to forged HTTP requests, because no CSRF token validation is applied to those endpoints. Any Joomla site running a vulnerable iCagenda release allows an attacker to trigger registrations or other frontend mutations on behalf of an authenticated visitor who is socially engineered into loading a crafted page. No public exploit has been identified at time of analysis, and the vendor has addressed the issue in version 4.0.11.
Unauthenticated path traversal in the token-optimizer-mcp dashboard server (npm package @ooples/token-optimizer-mcp v5.0.1) allows any network-accessible attacker to read arbitrary .jsonl files from the server's filesystem by supplying a crafted sessionId parameter to /api/session-summary or /api/session-events. The CVSS vector (PR:N, AV:N, AC:L, UI:N) confirms zero authentication or user interaction is required, and a working proof-of-concept demonstrating successful out-of-bounds file exfiltration has been publicly disclosed in GHSA-76pc-mqxp-3rq5. No active exploitation has been confirmed by CISA KEV, but the trivial exploitation complexity and public PoC make this an immediate priority for any internet-exposed deployment.
The ckan_get_mqa_quality and ckan_get_mqa_quality_details tools in CKAN MCP Server prior to 0.4.112 accept a server_url parameter validated only by a prefix-anchored regex, enabling attackers to bypass the dati.gov.it allowlist and redirect HTTP requests to attacker-controlled infrastructure via suffix-host (dati.gov.it.attacker.com) or RFC 3986 userinfo (dati.gov.it@attacker.com) techniques. The root cause is CWE-20 improper input validation - the regex tests only the string prefix, not the parsed hostname. No active exploitation has been identified and the vulnerability is not in CISA KEV; CVSS 5.3 reflects a medium-severity information disclosure path with no patch bypass complexity.
Undertow's HTTP response header writing path silently truncates 16-bit Unicode characters to 8-bit bytes via a narrowing cast in the `writeString()` method, enabling remote unauthenticated attackers to inject ASCII control characters or special symbols into response headers when an application passes unsanitized user-controlled input into those headers. Affected Red Hat distributions include RHEL 8/9/10, JBoss EAP 7, Red Hat Build of Apache Camel for Spring Boot 4, and Red Hat Single Sign-On 7, as reported by Red Hat via Bugzilla #2516038. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Path traversal in DTStack Taier 1.4.0's UploadController allows privileged remote attackers to write files outside the intended upload directory by supplying a crafted filename containing sequences such as '../' or absolute paths. The commit diff confirms that `MultipartFile.getOriginalFilename()` output was concatenated directly into a filesystem path without any sanitization before the fix. The CVSS 4.0 PR:H rating constrains exploitation to authenticated high-privilege users; no public exploit code or CISA KEV listing exists at time of analysis.
Path traversal in DTStack Taier 1.4.0 allows an authenticated administrative user to supply a crafted clusterName containing directory-escape sequences during cluster creation, causing FileUtils.deleteDirectory to operate on arbitrary filesystem paths outside the intended temp directory. The CVSS 4.0 score of 5.1 with PR:H reflects the constrained attack surface: only users with cluster management privileges can trigger the flaw. No public exploit code or CISA KEV listing exists at time of analysis.
Access control bypass in the iCagenda Event Scheduler Extension for Joomla (all versions prior to 4.0.11) permits authenticated backend operators to enumerate Joomla user profiles beyond their intended permission scope. An operator account granted access exclusively to the `com_icagenda` component - a tightly restricted, low-trust role - can leverage the flaw to query the broader Joomla user database, violating the principle of least privilege. No public exploit has been identified at time of analysis, and the CVSS 4.0 score of 5.1 (Medium) reflects the high privilege prerequisite and limited confidentiality impact.
Cross-site request forgery in KUNBUS PiCtory 2.16.0's web-based configuration backend allows remote unauthenticated attackers to perform destructive state-changing operations - including deletion of project and configuration files and resetting the control runtime - by inducing an authenticated operator's browser to submit crafted requests. This affects industrial OT environments where PiCtory manages Revolution Pi controller configurations. No public exploit has been identified at time of analysis, but the impact in ICS/OT contexts extends to potential disruption of control operations even at a 'low' CVSS integrity/availability rating.
Stored cross-site scripting in Grav CMS versions 1.5.2 through 2.0.12 allows authenticated page editors lacking admin.super privileges to bypass the built-in XSS filter by embedding a literal `>` character inside a quoted HTML attribute value, exploiting a regex blind spot in `Security::detectXss()` that causes the detector to consider the tag closed while browsers continue parsing it and execute a trailing event handler such as `onerror`. The crafted payload is accepted, persisted server-side, and executes in the site origin every time any visitor - including unauthenticated users - views the affected page. No public exploit has been identified at time of analysis; vendor-released patch is available in Grav 2.0.13.
Stored cross-site scripting in the Grav Form Plugin before version 9.1.15 allows authenticated form authors to inject arbitrary HTML and JavaScript into radio and toggle field option labels, which then execute in the browsers of any visitor or administrator rendering that form. The root cause is Twig's |raw filter being applied to user-controlled label content, bypassing the template engine's automatic output encoding. No public exploit code or active exploitation has been identified at time of analysis; the CVSS 4.0 score of 5.1 accurately reflects the requirement for prior authentication with form-authoring privileges.
Out-of-bounds read in Capstone's cs_insn_name() public API crashes host processes when the M68K or RISCV architecture backends receive caller-controlled invalid instruction IDs that bypass missing or incomplete bounds checks. Affected are all Capstone deployments prior to 6.0.0-Alpha9 where those two architecture handles are in use and instruction ID input is not sanitized by the calling application. The demonstrated impact is strictly a denial-of-service crash; no code execution or data exfiltration was shown, and no public exploit or active exploitation has been identified at time of analysis.
Open redirect in chi (go-chi/chi) versions before 5.2.2 allows Host header injection via the RedirectSlashes middleware, enabling attackers to redirect users to arbitrary external domains for phishing and credential theft. Applications using the RedirectSlashes middleware that expose their chi router to environments where the Host header can be forged are directly at risk. No public exploit is identified in CISA KEV; however, a functional proof-of-concept is documented in the GHSA advisory, and the GHSA itself characterizes real-world exploitability as lower-severity because standard browsers and email clients cannot be used to manipulate the Host header.
Broken or risky cryptographic algorithm use in Johnson Controls TL280 communicator firmware exposes device communications to cryptanalytic attack, affecting all versions before 5.63. An unauthenticated network attacker who can satisfy specific attack prerequisites - most likely a man-in-the-middle network position - can achieve limited confidentiality, integrity, and availability impact against communications to and from the device. No active exploitation is confirmed (CISA KEV absent, SSVC exploitation status: none), and automatable exploitation is assessed as unlikely due to the AT:P requirement in the CVSS 4.0 vector.
Time-based SQL injection in the affiliate-toolkit WordPress plugin (all versions up to and including 3.8.8) enables authenticated administrators to blindly enumerate and extract arbitrary data from the WordPress database by manipulating the unsanitized `orderby` parameter in template administrative pages. The impact is limited to confidentiality - database modification and denial-of-service are not achievable via this vector. No public exploit code has been identified at time of analysis, and no CISA KEV listing exists, consistent with the high authentication barrier (PR:H) that substantially constrains real-world exploitability.
Red Hat Quay's notification API exposes sensitive integration secrets - including webhook URLs, Slack tokens, and email addresses - to any authenticated repository administrator who can enumerate or guess a target notification's UUID. The flaw is an Insecure Direct Object Reference (CWE-639): the notification UUID acts as the sole access control key, with no ownership check verifying that the requesting admin belongs to the repository whose notification is being accessed. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, but the confidentiality impact is High per CVSS due to the sensitivity of the exposed secrets.
Denial of service in dnsmasq's DNSSEC validation code allows an attacker who operates any DNSSEC-signed authoritative zone to permanently hang the dnsmasq process with a single crafted DNS response, killing all DNS resolution for every client served by that instance. Affected deployments include dnsmasq as packaged in Red Hat Enterprise Linux 6 through 10 and Red Hat OpenShift Container Platform 4. No public exploit code or active exploitation has been identified at time of analysis; the assigned CVSS score of 4.4 (Medium) carries a notable inconsistency between the stated local attack vector and the network-delivered attack mechanism described.
IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 expose a security bypass whereby a remote low-privilege authenticated attacker can disable server-side input validation by supplying a specific request parameter, then submit otherwise-rejected malicious input. The vulnerability is rooted in CWE-693 (Protection Mechanism Failure), meaning a core defensive control can be switched off at the attacker's discretion rather than enforced by the server. With CVSS 6.3 Medium, partial confidentiality, integrity, and availability impacts are possible; no public exploit code or active exploitation has been identified at time of analysis.
QoS policy authorization bypass in OpenStack Octavia through version 18.0.0 permits authenticated tenant users to associate another project's Quality of Service policy with an amphora they control, blocking the legitimate policy owner from deleting that resource. The vendor confirms all Octavia deployments are affected, making this a universal tenant-isolation concern for multi-tenant OpenStack clouds. No active exploitation or public exploit code has been identified at time of analysis; the CVSS 4.3 Medium score reflects limited impact scope - integrity only, with no confidentiality or availability exposure.
Cross-site request forgery in the Astro Booking Engine WordPress plugin (all versions ≤ 1.4.0) enables unauthenticated remote attackers to wipe all plugin settings by tricking an authenticated administrator into following a malicious link. The root cause is missing nonce validation on the options-deletion handler - a textbook CWE-352 pattern - allowing the plugin to execute state-changing operations without confirming request origin. No active exploitation has been confirmed (not in CISA KEV) and no public proof-of-concept has been identified, positioning this as a legitimate remediation item rather than an emergency response priority.
Out-of-bounds write in Zephyr RTOS's LoRaWAN Fragmented Data Block Transport service corrupts the Semtech/LoRaMAC-node decoder's internal MatrixM2B recovery-matrix state when a DATA_FRAGMENT command carries frag_index_n = 0, underflowing the 1-indexed counter arithmetic to array index -1. Impact is constrained to denial of an active FUOTA (Firmware Update Over The Air) session and decoder state corruption - not code execution - despite 'RCE' appearing in the intelligence metadata tags, which directly contradicts the CVE description. No public exploit has been identified and this vulnerability is not listed in CISA KEV.
Information disclosure in CKAN MCP Server prior to v0.4.112 exposes raw upstream HTTP response bodies, internal hostnames, IP addresses, database error messages, and stack fragments to callers via unsanitized error paths. The flaw is reachable over the network without authentication (CVSS AV:N/PR:N) but requires high complexity, specifically the ability to direct the server at a non-CKAN host - either legitimately or via SSRF chaining. No public exploit code has been identified at time of analysis, and a vendor-released patch is available at v0.4.112.
Incorrect default file permissions on /etc/vsftpd.conf in TrendNet TEW-813DRU firmware 1.01b01 allow a remote low-privileged attacker to manipulate FTP server configuration, resulting in low-severity integrity compromise. The affected product is end-of-life and will receive no vendor patch. No public exploit code or active exploitation has been identified at time of analysis, and the CVSS 4.0 score of 2.3 reflects the high attack complexity and minimal impact scope.
Path traversal in wvp-GB28181-pro 2.7.4-20260107 exposes arbitrary server-side files through the Log File Download Endpoint in LogController.java, where the unsanitized `fileName` parameter allows directory escape sequences to be supplied by authenticated remote attackers. A public proof-of-concept exploit has been released per the CVSS 4.0 supplemental metric (E:P) and VulDB submission, lowering the bar for exploitation. Impact is limited to low-severity confidentiality loss with no integrity or availability effects, consistent with the CVSS 4.0 score of 2.1 and a PR:L/VC:L vector.
Integer truncation in Capstone's WebAssembly disassembly backend allows a crafted br_table instruction to cause either an infinite decode loop or misaligned parser advancement, undermining both availability and parser integrity in any application that passes attacker-controlled WASM bytes to cs_disasm() or cs_disasm_iter(). All Capstone versions prior to 6.0.0-Alpha9 are affected. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; the CVSS 4.0 score of 2.0 reflects the local attack vector and constrained real-world impact.
Account takeover in Authorizer's OAuth callback handler allows an unauthenticated attacker to pre-stage persistent backdoor access to any victim account by registering an unverified email address before the victim completes a routine OAuth login. The attack exploits a trust boundary violation in `internal/http_handlers/oauth_callback.go` (lines 125-219): the handler merges any incoming OAuth identity into the first database account matching by email, auto-verifies that account's email, and never invalidates the original password - leaving the attacker's credential fully active. No public exploit code has been independently confirmed, but the GHSA advisory contains a complete, line-referenced attack chain that makes independent reproduction trivial.
CVE-2026-66021 is a vulnerability reported by Ubuntu (vendor disclosure) for which no description, CVSS score, CVSS vector, or CWE classification has been made available in the provided intelligence data. The affected component, attack vector, and impact cannot be characterized without a description. No exploitation status, EPSS probability, KEV listing, or POC availability data was supplied. Analysis is severely constrained by the absence of substantive intelligence.
CVE-2026-63626 concerns a bounds-checking deficiency in the built-in TCP/IP stack's PPP (Point-to-Point Protocol) IPV6CP option parsing code in the Linux kernel, as reported by Ubuntu's vendor security team. IPV6CP is the IPv6 Control Protocol negotiated during PPP link establishment; a flaw in parsing its options could allow malformed input to exceed expected memory boundaries. No CVSS score, vector, or CWE classification has been published at time of analysis, leaving severity and exploitability unconfirmed.
