CVE-2026-22880 May 21, 08:22 MEDIUM This Month

SSO authentication callback origin validation failure in Mattermost Mobile Apps enables cross-server credential theft across multiple release branches (≤11.1.3, ≤11.3.2, ≤11.0.4, ≤10.11.11, ≤2.0.37). An attacker operating a malicious Mattermost server can relay the SSO authorization code exchange through a victim's mobile application to authenticate against a separate, legitimate Mattermost server - stealing valid session credentials without the victim's awareness. No public exploit has been identified at time of analysis, and CVSS AC:H constrains this to targeted, engineered attacks rather than opportunistic mass exploitation.

Sandbox policy bypass in Twig's deprecated `{% sandbox %}{% include %}` tag path allows template authors to access every filter, function, and tag registered in the environment, regardless of the configured SecurityPolicy. This is an incomplete fix for CVE-2024-45411 (GHSA-6j75-5wfj-gh66): the prior fix added an explicit `checkSecurity()` re-invocation in `CoreExtension::include()` but did not update the compiled output of the `{% sandbox %}{% include %}` syntax, leaving it without the same guard. Twig versions prior to 3.26.0 using this deprecated tag in applications that allow user-controlled template authorship are affected. No public exploit has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog.

Improper authorization in NocoDB (npm/nocodb ≤ 0.301.3) allows unauthenticated network attackers holding only a shared-base UUID to enumerate base members and inject arbitrary email addresses as permanent authenticated base members. The invited account redeems the invite through the normal signup flow, obtains a persistent JWT scoped to the target base, and retains that access even after the base owner revokes the shared link - effectively converting ephemeral anonymous share access into durable authenticated membership.

NocoDB's refresh-token cookie in versions up to and including 0.301.3 was misconfigured in `setTokenCookie` - issued with only `httpOnly: true` and no `secure` or `sameSite` attributes - exposing two distinct attack paths: cookie interception over plain HTTP networks and CSRF against the `POST /api/v2/auth/token/refresh` endpoint, which returns a new JWT without validating any CSRF token. Because refresh tokens carry multi-day expiry windows via `NC_REFRESH_TOKEN_EXP_IN_DAYS`, successful exploitation yields a long-lived credential for follow-on account access.

Unbounded formatter memoization in twig/intl-extra versions prior to 3.26.0 enables memory exhaustion denial of service on persistent PHP worker runtimes. The IntlExtension caches every unique combination of template filter arguments (locale, pattern, grouping_used, attrs, etc.) as ICU formatter objects with no eviction policy; because ICU allocates its backing buffers outside the Zend memory manager, this growth entirely bypasses PHP's memory_limit directive. On long-running runtimes such as RoadRunner, Swoole, FrankenPHP worker mode, and ReactPHP - where a single Twig\Environment persists across requests - the cache accumulates indefinitely across all requests, making targeted or incidental denial of service achievable without any authentication.

Cross-site scripting in twig/markdown-extra and twig/cssinliner-extra arises from three filters - html_to_markdown, markdown_to_html, and inline_css - being incorrectly registered with is_safe => ['all'], which instructs Twig's autoescaper to suppress output encoding in every context including JS, CSS, and URL. When attacker-controlled content flows through these filters and the result is interpolated into a non-HTML context such as an inline script block, the autoescaper emits the raw output verbatim, enabling XSS without the developer ever using the explicit |raw bypass. Notably, html_to_markdown has an additional entity-decoding gadget via league/html-to-markdown that converts encoded HTML entities back to live markup during code span generation, creating a secondary injection path even in HTML contexts.

Cross-site scripting in Twig's PHP templating engine allows attacker-controlled HTML markup to bypass autoescaping when rendered through the `|spaceless` filter.

Stored cross-site scripting in the Drupal 7 Term Reference Tree module (versions 7.x-1.x through 7.x-1.11) exposes two distinct injection vectors in its widget and formatter rendering pipeline, both exploitable by any authenticated user with taxonomy term edit permissions. Vector A triggers when the Token module is enabled and token display templates are configured, allowing attacker-controlled term description output to render unsanitized.

An attacker who can deliver a crafted POST request to a victim's browser can execute arbitrary JavaScript in the victim's session context, enabling session hijacking or credential theft. The vendor-confirmed fix (v3.44.2) was released as a critical security update resolving 88 total vulnerabilities; no public exploit or CISA KEV listing is identified at time of analysis.

CVE-2026-48215 May 21, 17:09 MEDIUM PATCH This Month

Reflected XSS in Open ISES Tickets (versions before 3.44.2) allows network-based attackers to inject arbitrary JavaScript through the frm_id POST parameter in circle.php, requiring victim interaction with a crafted link or form. The vulnerability executes malicious scripts in the victim's browser context with low-scope impact to confidentiality and integrity. No public exploit code or active exploitation has been identified at time of analysis. VulnCheck reported this as one of 69 XSS vulnerabilities patched in the v3.44.2 security release, which addressed 88 total security issues including SQL injection and hardcoded credentials.

CVE-2026-48214 May 21, 17:09 MEDIUM PATCH This Month

Reflected XSS in Open ISES Tickets before v3.44.2 enables JavaScript injection through the unsanitized ticket_id POST parameter in add_nm.php, which is embedded without encoding into both an HTML form input value attribute and an inline JavaScript string literal - two distinct injection contexts. When a victim renders the malicious response, attacker-controlled script executes in their browser with potential to steal session tokens or perform actions under their identity. No public exploit exists and the vulnerability is not in CISA KEV, but the v3.44.2 release notes reveal 88 co-patched security defects (including 19 SQL injection issues and hardcoded secrets), meaning any unpatched deployment faces compounded, systemic risk far beyond this single CVE.

CVE-2026-48213 May 21, 15:51 MEDIUM PATCH This Month

Reflected cross-site scripting in Open ISES Tickets before 3.44.2 allows injection of arbitrary JavaScript via the ticket_id POST parameter in add.php, which is echoed unsanitized into an HTML form input value attribute. The CVSS 4.0 vector scores this at 5.1 with no privileges required and active user interaction needed, though the CVE description characterizes attackers as authenticated - a discrepancy discussed in the risk section. No public exploit code or CISA KEV listing exists at time of analysis. This vulnerability is one of 69 XSS issues patched in a single v3.44.2 release that also addressed 19 SQL injection flaws and 5 hardcoded secrets, suggesting systemic insecure coding practices across the codebase.

CVE-2026-5091 May 21, 21:07 MEDIUM PATCH This Month

Timing attack exposure in Catalyst::Plugin::Authentication (all versions through 0.10024) allows side-channel inference of stored passwords or password hashes through non-constant-time string comparison. The Perl built-in `eq` operator short-circuits on first character mismatch, leaking measurable timing differences that an attacker can exploit statistically across many authentication attempts to progressively recover credential material. No public exploit has been identified at time of analysis and SSVC exploitation status is confirmed as none, though the cryptographic weakness is real and patch availability is confirmed upstream.

Reflected cross-site scripting in Open ISES Tickets before version 3.44.2 allows an attacker to inject arbitrary JavaScript via the unsanitized _type POST parameter in landb.php, which is echoed directly into an HTML form hidden input value attribute without encoding. When a victim renders the crafted response, the injected script executes in their browser context, enabling session hijacking, credential theft, or forced action on behalf of the victim. This CVE is one of 69 XSS vulnerabilities addressed in the v3.44.2 critical security update; no public exploit has been identified at time of analysis and it is not listed in CISA KEV.

CVE-2026-44073 May 21, 07:35 MEDIUM PATCH This Month

Privilege retention in Netatalk 1.5.0 through 4.4.2 results from auth modules silently ignoring failures of the seteuid() system call, allowing an authenticated network attacker to operate with unintended elevated privileges. When seteuid() fails-due to resource exhaustion, OS limits, or specific system configurations-the process continues execution under its original (higher) UID rather than the intended reduced privilege level, exposing file system objects or operations the user should not access. No public exploit code has been identified at time of analysis, and the issue is not listed in CISA KEV, but the vendor has confirmed the flaw and released a fix in version 4.5.0.

CVE-2026-46561 May 21, 19:54 MEDIUM PATCH GHSA This Month

Redirect-based SSRF bypass in pyload-ng's parse_urls API allows authenticated attackers with ADD permission to probe internal network services and cloud metadata endpoints by chaining an open redirect through an attacker-controlled host. The prior SSRF fix (commit 33c55da, GHSA-7gvf-3w72-p2pg) correctly hardened HTTPChunk but left HTTPRequest used by RequestFactory.get_url() with allow_private_ip=True, rendering the is_global_host() check on the initial URL ineffective against 302 redirects to private IP space. A public proof-of-concept exploit exists demonstrating exfiltration of AWS IMDSv1 metadata; no public exploit identified at time of analysis for active in-the-wild exploitation, and CVE-2026-46561 is not listed in the CISA KEV catalog.

CVE-2026-4811 May 21, 02:27 MEDIUM This Month

Stored Cross-Site Scripting in the WPB Floating Menu & Categories WordPress plugin (all versions through 1.0.8) permits authenticated attackers holding Editor-level privileges or higher to inject arbitrary JavaScript via the 'Icon CSS Class' category field. The injected payload persists in the database and executes in the browser of any site visitor who loads a page containing the affected floating menu component, enabling session hijacking or credential harvesting against arbitrary users including administrators. No public exploit has been identified at time of analysis, and the plugin is not listed in the CISA KEV catalog; the CVSS 4.9 Medium score reflects the significant mitigation provided by the high-privilege prerequisite.

CVE-2026-41999 May 21, 09:27 MEDIUM PATCH This Month

Incorrect view selection in PowerDNS Authoritative Server when processing TCP PROXY protocol requests exposes DNS records intended for a different network segment to remote unauthenticated attackers, producing both unauthorized information disclosure and limited integrity impact. Deployments running split-horizon DNS via the Views feature alongside TCP PROXY protocol support are the specific affected population. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV; however, the attack concept requires no authentication and no user interaction, making it relevant wherever both features are co-deployed.

CVE-2026-46609 May 21, 20:43 MEDIUM PATCH GHSA This Month

HTML injection (stored XSS) in the Umbraco CMS Backoffice confirmation dialog allows authenticated low-privilege users to inject arbitrary HTML into an input field that is subsequently rendered without output encoding when a confirmation dialog is triggered. Affected versions span nuget/Umbraco.Cms 14.0.0 through 17.3.5. The CVSS score of 4.6 reflects the constrained attack surface: exploitation requires an authenticated Backoffice session and a second victim user to interact with the dialog, limiting blast radius to the admin panel rather than public-facing surfaces. No public exploit identified at time of analysis and this CVE does not appear in the CISA KEV catalog.

Race condition in Netatalk's privilege toggle mechanism exposes AFP file server hosts to local privilege abuse across versions 2.2.5 through 4.4.2. The non-reentrant privilege toggle function can be exploited by a low-privileged local user who wins a narrow timing window to read, modify, or disrupt data at a transiently elevated privilege level. No public exploit code exists and the issue is not listed in CISA KEV; real-world risk is constrained by the requirement for local access and high attack complexity. Vendor-released patch is available in version 4.5.0.

CVE-2026-46671 May 21, 21:32 MEDIUM PATCH GHSA This Month

Path traversal in the Rust crate onenote_parser (versions before 1.1.1) enables an attacker who supplies a malicious `.onetoc2` notebook table-of-contents file to direct `Parser::parse_notebook` to open arbitrary files on the host filesystem outside the intended notebook directory. While direct content exfiltration is constrained by the parser aborting when a target file fails to parse as a OneNote section, file-existence probing and denial-of-service via large or special files (e.g., named pipes, device nodes) remain viable attack outcomes. No public exploit has been identified and no confirmed active exploitation exists; vendor-released patch version 1.1.1, published 2026-05-15, resolves the issue.

CVE-2026-46542 May 21, 19:45 MEDIUM PATCH GHSA This Month

Process crash in the nimiq-keys Rust crate (versions below 1.4.0) occurs when the Ed25519 multisig delinearization path receives a 32-byte public key that is length-valid but does not represent a valid point on the Edwards25519 curve, triggering a Rust `.unwrap()` panic that kills the hosting wallet process. Affected users are those running the Nimiq web-client WASM library or nimiq-wallet crate who can be persuaded by an attacker to include a crafted key in a multisig setup; validator nodes and all consensus infrastructure are explicitly out of scope. No public exploit has been identified at time of analysis, and no KEV listing exists, indicating this has not been broadly weaponized.
