Optimole Optimize Images In Real Time
Monthly
Unauthenticated stored XSS in Optimole WordPress plugin (≤4.2.2) allows attackers to inject malicious scripts via the srcset descriptor parameter in the /wp-json/optimole/v1/optimizations REST endpoint. Despite HMAC signature validation, authentication tokens are exposed in frontend HTML, enabling exploitation. Injected payloads persist in WordPress options table via transients and execute when victim browsers render affected pages. No public exploit identified at time of analysis.
Reflected Cross-Site Scripting (XSS) in Optimole - Optimize Images in Real Time WordPress plugin versions up to 4.2.3 allows unauthenticated attackers to inject arbitrary JavaScript through malicious URL paths. The vulnerability stems from insufficient output escaping in the get_current_url() function, which are then inserted into JavaScript code via str_replace() without proper JavaScript context escaping in replace_content(). An attacker can craft a malicious link that, when clicked by a WordPress user, executes injected scripts in the context of the user's browser session with CVSS 6.1 (Medium) severity.
