What is CVE-2026-121588?

TeXlyre prior to version 0.13.5 is vulnerable to a stored cross-site scripting (XSS) flaw. This issue arises when attackers are able to embed malicious scripts within recipe icons, persuading victims to import these deceptive icons. Such an action permits persistent access to local projects, as well as repository credentials, potentially compromising sensitive information. Users of affected versions should apply available patches to mitigate these security risks.
