This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The contributor comment is stored in a plugin-managed custom table, bypassing WordPress core's wp_kses_post filter, and the save_post hook fires without a nonce check, meaning any user who can edit posts can exploit this without further preconditions.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":35,"depthScoreParts":{"impact":35.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
