Vulnerability Details

Description Symfony's "#[IsGranted('...')]", "#[IsSignatureValid]", and "#[IsCsrfTokenValid(...)]" attributes allow you to define a "methods: [...]" argument to only enforce these checks for the listed HTTP methods and skip them otherwise. E.g. an attribute defining "methods: ['GET']" would be ignored for a "HEAD" request. On the other hand, Symfony's router (and HTTP semantics generally) serves "HEAD" requests using the "GET" handler. Therefore, a controller protected by e.g. "#[IsGranted('ROLE_ADMIN', methods: ['GET'])]" can be reached via "HEAD" with the authorization check silently skipped. Even if the "HEAD" request won't get any response content, response headers leak ("Content-Length", "Location", custom headers). Also, the controller still executes and any side effects (DB writes, state changes) occur. Resolution When adding "GET" in the "methods" option of these attributes, Symfony now also include the "HEAD" method automatically. The patch for this issue is available "here" (symfony/symfony@fa8d5c6) for branch 7.4. Credits Symfony would like to thank Claude Mythos Preview (via Project Glasswing) for reporting the issue and Alexandre Daubois for fixing it.

CVE-2026-45070

Vulnerable Library - symfony/mime-v8.0.0

Allows manipulating MIME messages

Library home page: https://api.github.com/repos/symfony/mime/zipball/7576ce3b2b4d3a2a7fe7020a07a392065d6ffd40

Dependency Hierarchy:

  • vich/uploader-bundle-v2.9.1 (Root Library)
    • symfony/mime-v8.0.0 (Vulnerable Library)

Found in base branch: develop

Vulnerability Details

Description "Symfony\Component\Mime\Header\ParameterizedHeader" (and the related parameter handling reachable from "Symfony\Component\Mime\Header\Headers") is responsible for serializing structured headers such as "Content-Type" and "Content-Disposition", which carry "key=value" parameters (e.g. "Content-Disposition: attachment; filename="x""). RFC 2045 / RFC 5322 require parameter names to be "tokens": a restricted ASCII subset that excludes whitespace, CR/LF, and the "tspecials" set. Symfony's parameter handling validates and properly encodes parameter values, but does not validate parameter names: the supplied name is emitted verbatim into the serialized header. A caller that derives a parameter name from untrusted input, e.g. an application that lets a user influence a "Content-Disposition" parameter name, can include "\r\n" or other non-token bytes inside the name, terminating the current header and injecting additional headers in the rendered message. This is the classic CRLF / header-injection primitive applied to the parameter-name slot. Resolution "ParameterizedHeader" now rejects parameter names that contain bytes outside the RFC "token" character class. The patch for this issue is available "here" (symfony/symfony@e62ea21) for branch 5.4. Credits Symfony would like to thank Fabian Fleischer for reporting the issue and Alexandre Daubois for fixing it.

CVE-2026-45067

Vulnerable Library - symfony/mime-v8.0.0

Allows manipulating MIME messages

Found in base branch: develop

Vulnerability Details

Description "Symfony\Component\Mime\Address" is the value-object every Symfony Mailer address (to/cc/bcc/from/reply-to) flows through; its constructor is documented as validating the address and throwing on invalid input, so developers treat it as a security boundary. The constructor accepts email addresses whose local-part (the part before "@") is an RFC-5322 quoted string containing raw "\r\n" bytes, e.g. ""x\r\nBcc: attacker@evil"@⁠example.com". The stored address is later emitted verbatim into (1) the rendered message headers and (2) "SmtpTransport"'s "MAIL FROM:<...>" / "RCPT TO:<...>" protocol lines, turning the embedded CRLF into a new mail header and/or a new SMTP command. Resolution The "Address" constructor now rejects addresses containing line breaks. The patch for this issue is available "here" (symfony/symfony@dc2dbd2) for branch 5.4. Credits We would like to thank Claude Mythos Preview (via Project Glasswing) for reporting the issue and providing the fix.
