WebauthnAuthenticator leaks sensitive HTTP headers through INFO-level logs
GitHub lists this reviewed advisory for web-auth/webauthn-symfony-bundle. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
web-auth/webauthn-symfony-bundle
source listed< 5.3.4
## Impact `Webauthn\Bundle\Security\Http\Authenticator\WebauthnAuthenticator` logs the full `Symfony\Component\HttpFoundation\Request` object inside the log context of both `onAuthenticationSuccess()` and `onAuthenticationFailure()` at INFO level: ```php $this->logger->info('User has been authenticated successfully with Webauthn.', [ 'request' => $request, 'firewallName' => $firewallName, 'identifier' => $token->getUserIdentifier(), ]); $this->logger->info('Webauthn authentication request failed.', [ 'request' => $request, 'exception' => $exception, ]); ``` `Request::__toString()` returns the raw HTTP message, including every request header. As soon as the configured logger normalises or stringifies the context (default behaviour for `LineFormatter`, `JsonFormatter` via `NormalizerFormatter`, etc.), sensitive headers such as `Cookie` (session identifier), `Authorization` and any custom auth header are written to the log stream in clear text. Applications that forward logs to centralised platforms (ELK, Splunk, Datadog and similar) are particularly exposed: log access is typically broader than application access, which can allow log readers to hijack authent

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
- vendor patch
The original advisory lists fixed boundaries 5.3.4 for web-auth/webauthn-symfony-bundle. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.

Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
