FKIE_CVE-2026-118514

Vulnerability from fkie_nvd - Published: 2026-11-06 15:17 - Updated: 2026-11-06 21:40
Severity
6.3 (Medium) - CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N
Summary
In 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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
