Unauthenticated script execution via undisclosed input path
Published Sep 3, 2026 · Updated Sep 3, 2026
Cross-site scripting in Advanpix WP QuickLaTeX 3.8.8 and earlier allows remote attackers to execute script via unspecified input. Patchstack has not disclosed the affected handler or parameter, nor how untrusted input reaches an HTML or script execution context. No account is required, but a victim must interact with attacker-controlled content; successful execution runs script in the victim's browser context.
