GHSA-GW25-M53R-QH88 SiYuan: path traversal via /export/temp/ short-circuit branch (incomplete fix for the export-disclosure hardening, GHSA-6865-qjcf-286f)

Summary SiYuan's /export/ file handler was hardened against export disclosure issue 12213 by adding an IsSubPathexportBaseDir, fullPath check and an IsSensitivePath check in commit bb481e1. These guards were added only to the main branch of the handler. The handler begins with a short-circuit...

CVE-2026-11430

Grav CMS’s scheduler-webhook plugin contains an authentication bypass in the webhook token check. When the webhook feature is enabled but no webhookToken is configured, a conditional short-circuit skips token validation, allowing an unauthenticated remote attacker who can reach POST /scheduler/we...

PSF-2026-34

Element.findall and fully-consumed Element.iterfind exhibit On^2 time complexity when using XPath index predicates e.g. 1, last, last-N on XML documents with many same-tag siblings. Element.find is only affected when the first match is near the end of the sibling list, such as with last or...

Netty: Security Control Bypass via CORS Short-Circuit Failure

Summary Netty's CorsHandler provides a shortCircuit configuration designed to reject unauthorized cross-origin requests immediately, acting as a security control before requests reach the application. However, due to a logical operator error in the origin evaluation process, this protection can b...

CVE-2026-56746 Netty has a Security Control Bypass via CORS Short-Circuit Failure

Netty is a network application framework for development of protocol servers and clients. Versions 4.2.0.Final through 4.2.15.Final and 4.1.0.Final through 4.1.135.Final, are vulnerable to security control bypass during the origin evaluation process. CorsHandler provides a shortCircuit...

CVE-2026-56746

Netty (versions 4.2.0.Final–4.2.15.Final and 4.1.0.Final–4.1.135.Final) contains a security control bypass in CorsHandler’s origin evaluation due to a logical operator error. An attacker can bypass the short-circuit protection by sending Origin: null, causing unauthorized requests to reach the ba...

CVE-2026-57852 Authentication Bypass via Null Short-Circuit in Grav CMS Scheduler Webhook Token Check

Grav CMS scheduler-webhook plugin contains an authentication bypass vulnerability that allows unauthenticated remote attackers to trigger configured scheduled jobs by exploiting a short-circuit logic flaw in the webhook token validation. Attackers can send a single unauthenticated POST request to...

CVE-2026-41240

DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Versions prior to 3.4.0 have an inconsistency between FORBIDTAGS and FORBIDATTR handling when function-based ADDTAGS is used. Commit c361baa added an early exit for FORBIDATTR at line 1214. The same fix was not...

GHSA-5PV5-XH52-HVRP uutils coreutils has an Incorrect Short Circuit Evaluation Issue

A logic error in the expr utility of uutils coreutils causes the program to evaluate parenthesized subexpressions during the parsing phase rather than at the execution phase. This implementation flaw prevents the utility from performing proper short-circuiting for logical OR | and AND & operation...

DOMPurify: FORBID_TAGS bypassed by function-based ADD_TAGS predicate (asymmetry with FORBID_ATTR fix)

There is an inconsistency between FORBIDTAGS and FORBIDATTR handling when function-based ADDTAGS is used. Commit c361baa added an early exit for FORBIDATTR at line 1214: / FORBIDATTR must always win, even if ADDATTR predicate would allow it / if FORBIDATTRlcName return false; The same fix was not...

CVE-2026-35378

CVE-2026-35378 affects the expr utility in uutils coreutils. A logic error causes evaluation of parenthesized subexpressions during parsing instead of execution, preventing proper short-circuiting for OR/AND. Consequently, arithmetic errors (e.g., division by zero) in dead branches are raised as ...
