Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:HSummary
CVE-2026-35488 is a high-severity Exposed Dangerous Method or Function (CWE-749) vulnerability in Tandoor Recipes. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 31th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-35488 is a permission bypass vulnerability in Tandoor Recipes, an open-source application for managing recipes, planning meals, and building shopping lists. Versions prior to 2.6.4 are affected, specifically in the RecipeBookViewSet and RecipeBookEntryViewSet components. These use a CustomIsShared permission class whose has_object_permission() method returns True for all HTTP methods—including DELETE, PUT, and PATCH—without checking if the request.method is within SAFE_METHODS. This allows shared users to perform destructive actions on RecipeBooks, despite shared access being intended as read-only.
The vulnerability can be exploited by any authenticated user (PR:L) listed in a RecipeBook's shared list, over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation enables deletion or overwriting of the RecipeBook (I:H/A:H), with no confidentiality impact (C:N) and unchanged scope (S:U). The CVSS v3.1 base score is 8.1, mapped to CWE-749 (Exposed Dangerous Method or Function).
The issue is addressed in Tandoor Recipes version 2.6.4. Security practitioners should upgrade to this release for mitigation. Additional details are available in the GitHub release notes at https://github.com/TandoorRecipes/recipes/releases/tag/2.6.4 and the security advisory at https://github.com/TandoorRecipes/recipes/security/advisories/GHSA-xvmf-cfrq-4j8f.

Vulnerability Data
Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.4, RecipeBookViewSet and RecipeBookEntryViewSet use CustomIsShared as an alternative permission class, but CustomIsShared.has_object_permission() returns True for all HTTP methods — including DELETE, PUT, and…
more
PATCH — without checking request.method in SAFE_METHODS. Any user who is in the shared list of a RecipeBook can delete or overwrite it, even though shared access is semantically read-only. This vulnerability is fixed in 2.6.4.

V8.2.1
Mitigating Controls (NIST 800-53 r5) AI
Access enforcement directly stops unauthorized callers from invoking dangerous API methods or functions.
Least privilege restricts which users or processes may reach dangerous methods, limiting exposure.
Least functionality removes or disables non-essential dangerous methods from the exposed interface altogether.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing least-privilege authorization directly prevents unrestricted dangerous API methods.
Secure SDLC practices stop developers from exposing dangerous functions in the first place.
Vulnerability identification processes will surface exposed dangerous methods during assessment.
Logical access controls at the network/environment layer can limit reachability of exposed functions.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing can detect exposed dangerous functions, but does not prevent their initial introduction.
Restricting privileged utility programs reduces exposure of dangerous functions, but does not eliminate the underlying weakness.
Privileged access rights limit who can invoke dangerous methods, but do not address whether the method itself should exist.
Secure development life cycle requires removal or protection of dangerous APIs during design and coding.
Application security requirements can mandate that dangerous methods are not exposed in interfaces.
Secure architecture principles discourage exposing dangerous functions, but do not guarantee their absence.
