CVE-2026-73382Network attack vector

Stored XSS via review content sanitization bypass

Published Aug 18, 2026 · Updated Aug 18, 2026

Cross-site scripting in Gemini Labs Site Reviews 8.2.0 and earlier allows remote attackers to execute script in rendered reviews. The 8.2.1 changelog identifies the flaw in review content, and the plugin renders stored review body text into the review template; the sanitization path for that field did not fully neutralize attacker-controlled markup before later display. No account is required where public review submission is exposed, but successful exploitation still depends on a victim viewing the poisoned review.
