CVE-2026-129140

CVSS 5.4 (medium) · published 2026-11-13

paicoding 1.0.0 through 1.0.3 contains a stored cross-site scripting vulnerability in image upload because ImageServiceImpl.validateStaticImg accepts SVG files, which are then served from the site origin when local storage is used. Authenticated attackers can upload script-bearing SVG images that execute when victims view them, stealing the non-HttpOnly f-session cookie to hijack accounts.

Weakness: CWE-79
