Last modified

CVE-2026-59965 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. Payload Plugins is a collection of plugins designed to enhance Payload CMS. In 0.7.0, @jhb.software/payload-alt-text-plugin exposes POST /api/alt-text-plugin/generate and POST /api/alt-text-plugin/bulk with a default guard that accepts any authenticated user, while alt-text/src/endpoints/generateAltText.ts and alt-text/src/endpoints/bulkGenerateAltTexts.ts call req.payload.findByID and req.payload.update without overrideAccess: false. EPSS estimates a 0.38% chance of exploitation in the next 30 days.

Description

Payload Plugins is a collection of plugins designed to enhance Payload CMS. In 0.7.0, @jhb.software/payload-alt-text-plugin exposes POST /api/alt-text-plugin/generate and POST /api/alt-text-plugin/bulk with a default guard that accepts any authenticated user, while alt-text/src/endpoints/generateAltText.ts and alt-text/src/endpoints/bulkGenerateAltTexts.ts call req.payload.findByID and req.payload.update without overrideAccess: false. Payload therefore defaults overrideAccess to true and skips the target collection's read and update access functions. An authenticated low-privilege user can supply id, collection, locale, and update values to read arbitrary protected upload documents and overwrite their alt and keywords fields, even when the collection permits those operations only to administrators. A control Local API call with overrideAccess: false is denied, confirming that the plugin endpoint bypasses otherwise effective collection rules. This vulnerability is fixed in 0.8.0.
