CVE-2026-75835: Missing Authorization in getgrav grav
CVE-2026-75835 is a critical missing authorization vulnerability in the Grav API plugin (getgrav/grav-plugin-api) versions before 1.0.14. The flaw exists in the userPassesAuthorize() function, which improperly authorizes requests by ignoring API key scopes and relying solely on the super-admin flag and ACL grants. This allows an authenticated attacker with a scoped API key from a privileged account to bypass scope restrictions and access UI metadata and item definitions that should be restricted, leading to information disclosure.
AI Analysis
Technical Summary
The Grav API plugin before version 1.0.14 contains a missing authorization vulnerability in the userPassesAuthorize() function within AbstractApiController.php. This function fails to verify the calling request's API key scopes and instead bases authorization decisions on the account's super-admin flag and ACL grants. Consequently, an attacker authenticated with a scoped API key minted on a privileged account can circumvent scope restrictions to access authorize-gated UI metadata and item definitions, such as sidebar, menubar, widget items, and users-list columns, row actions, and filter tabs. This results in unauthorized information disclosure.
Potential Impact
An authenticated attacker possessing a scoped API key derived from a privileged account can bypass intended scope restrictions. This leads to unauthorized access to sensitive UI metadata and item definitions that are normally protected, resulting in information disclosure. The vulnerability does not require privilege escalation or user interaction and has a high impact on confidentiality.
Mitigation Recommendations
A fix is available in Grav API plugin version 1.0.14 and later. Users should upgrade to version 1.0.14 or above to remediate this vulnerability. No additional mitigation steps are indicated.
