CVE-2026-59963 — Tandoor Recipes: Private recipe file and share-link authorization bypass in recipe utility API endpoints

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.10, recipe utility endpoints retrieve same-Space Recipe objects without invoking the private-recipe owner or sharing permission when an authenticated member of a shared Space supplies another member's private recipe identifier to AI import, file, external-link, or share-link endpoints. Request processing uses api/ai-import/, api/get_recipe_file/, api/get_external_file_link/, api/share-link/, CustomRecipePermission. The attack works because the endpoints read private recipe files, send file bytes to the configured AI provider, or create and disclose external links without object-level authorization, and api/share-link/ can create a public link when Space sharing is enabled. This can expose private recipe files and sensitive uploaded content to another same-Space user and to configured external services. This issue is fixed in version 2.6.10.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (TandoorRecipes Recipes).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
