Payload Plugins is a collection of plugins designed to enhance Payload CMS. From 0.3.0 until 0.4.0, @jhb.software/payload-cloudinary-plugin deployments with clientUploads enabled expose POST /api/cloudinary-generate-signature, whose handler in cloudinary/src/getGenerateSignature.ts passes attacker-controlled body.paramsToSign directly to cloudinary.utils.api_sign_request without a key allowlist, collection policy, timestamp freshness check, or configured-folder enforcement. Any authenticated Payload user can obtain a valid Cloudinary HMAC-SHA1 signature for unauthorized parameters such as overwrite, type, notification_url, invalidate, folder, and public_id. The signature can authorize asset replacement, upload visibility changes, callbacks to attacker-selected URLs, cache invalidation, and uploads outside the intended folder. The client-visible Cloudinary API key is expected by the upload design, but the unrestricted server-side signature supplies the authorization value needed to complete these operations. This vulnerability is fixed in 0.4.0.

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.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
