Information disclosure in the YMC Filter WordPress plugin before 3.11.3 lets unauthenticated remote attackers read the titles and content of private, draft, and other non-public posts by abusing a REST API endpoint that lacks proper authorization and fails to validate a user-supplied query parameter. WPScan reported the flaw, a public exploit exists, and a vendor patch is available; the CVSS 3.1 score is 7.5 reflecting high confidentiality impact with no integrity or availability effect.
SQL injection in the YMC Filter (YMC Smart Filter / Filter Grids) WordPress plugin lets remote attackers inject malicious SQL through unsanitized input, affecting all versions up to and including 3.11.5. Per the CVSS vector (PR:N), exploitation is unauthenticated and network-reachable, enabling database content disclosure and a scope change beyond the plugin's own data. No public exploit identified at time of analysis, and no EPSS score was supplied, so real-world exploitation prevalence is currently unmeasured.
Stored cross-site scripting in the YMC Filter WordPress plugin (all versions before 3.12.9) allows Author-role users to upload malicious SVG files whose embedded JavaScript executes in the browsers of any site user - including administrators - who views the file. A publicly available proof-of-concept exploit exists via WPScan, lowering the skill bar significantly for attackers who already hold an Author-level account. The EPSS score of 0.15% (5th percentile) indicates negligible automated exploitation activity, placing real-world risk primarily in multi-author WordPress environments where untrusted contributors hold Author-level access.
Stored cross-site scripting in the YMC Filter WordPress plugin (versions 3.6.0 through 3.12.7) enables any Contributor-level authenticated user to persistently inject arbitrary JavaScript into layout builder settings, which then executes in every site visitor's browser via an unsanitized public endpoint. The plugin compounds the flaw by failing to verify object ownership when saving layout settings, meaning low-privilege users can overwrite settings they do not control. A public proof-of-concept is available via WPScan; the vulnerability is patched in version 3.12.8.
