UBUNTU-CVE-2026-45075
Symfony PHP framework versions prior to 7.4.12 and 8.0.12 have a vulnerability where method-scoped security attributes configured for GET requests are bypassed for HEAD requests. This allows protected controllers to execute without proper authorization checks, potentially leaking headers or causing side effects. The issue is fixed in versions 7.4.12 and 8.0.12.
AI Analysis
Technical Summary
The vulnerability in Symfony affects method-scoped attributes #[IsGranted], #[IsSignatureValid], and #[IsCsrfTokenValid] that are configured to protect GET requests. Because Symfony routes HEAD requests to the GET handler but skips the attribute checks for HEAD, unauthorized execution of protected controllers is possible. This can lead to information leakage via headers or unintended side effects. The flaw is resolved in Symfony versions 7.4.12 and 8.0.12.
Potential Impact
Unauthorized HEAD requests can bypass security attribute checks intended for GET requests, allowing execution of protected controller logic. This may result in leakage of sensitive HTTP headers or unintended side effects in the application. There is no indication of privilege escalation or remote code execution from the provided data.
Mitigation Recommendations
Upgrade Symfony to versions 7.4.12 or 8.0.12 or later where this vulnerability is fixed. No other mitigation is indicated. Patch status is confirmed fixed in these versions.
