Descripción técnica

FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.227, the conversation_merge action records a failed authorization check for the target conversation in response['msg'] and then clears that value inside the source-conversation loop. An authenticated agent can merge a conversation they control into a target conversation in a mailbox they cannot access. The operation injects threads, attachments, and audit records into the unauthorized target and deletes the source conversation, but it does not disclose the target's existing contents. This issue is fixed in version 1.8.227.

——0In Symfony http-foundation prior to versions 5.4.56, 6.4.50, 7.4.23, and 8.1.11, Symfony\Component\HttpFoundation\RequestMatcher, and RequestMatcher\MethodRequestMatcher which replaces it from 6.2.x on, matches a request against a list of HTTP methods. These compared the request method to the list verbatim, while the router serves a HEAD request with the GET handler, as HTTP semantics require. This came after the incomplete fix of CVE-2026-45075 https://github.com/advisories/GHSA-6439-2f28-8p8q , which addressed the same gap in the #[IsGranted], #[IsSignatureValid] and #[IsCsrfTokenValid] attributes only. Security rules configured to apply only to GET requests could therefore be bypassed by sending a HEAD request to the same URL. Although HEAD responses contain no body, attackers could still access response headers and trigger the controller's execution, including any side effects. This issue also affects firewalls configured with methods: [GET]. A HEAD request would not match that firewall and could instead be handled by another matching firewall or no firewall at all. Applications using these vulnerable request matchers directly, including through a custom firewall request_matcher, could also be affected. The issue affects symfony/http-foundation through v5.4.55, v6.x through 6.4.49, v7.x through v7.4.22, and v8.x through v8.1.10.11h CVE-2026-1123408.2 ALT
