GHSA-7FQC-P256-7PWJ Steeltoe's static JWKS cache shared across schemes and never invalidated

Summary The JWT signing key cache in TokenKeyResolver uses kid as the sole cache key without namespacing by authority. In applications with multiple JwtBearer schemes pointing to different identity providers, a key fetched for one scheme can satisfy token validation for another. Additionally,...

CVE-2026-59096

Dapr Sentry’s OIDC discovery endpoint can be poisoned: the issuer and jwks_uri in /.well-known/openid-configuration are derived from the request Host via an attacker-controlled X-Forwarded-Host when oidc-allowed-hosts is not configured, and the document is cached for one hour. This allows remote ...

CVE-2026-59096 Dapr - OIDC Discovery Issuer and JWKS URI Injection via Unvalidated X-Forwarded-Host

Dapr Sentry's OIDC discovery endpoint derives the issuer and jwksuri of the /.well-known/openid-configuration document from the request Host, honoring an attacker-controlled X-Forwarded-Host header without validation when no allowed-hosts list is configured the default, and serves the document wi...

Security Bulletin: Path Traversal Vulnerability in File Component Leading to Arbitrary File Read and Authentication Bypass

Summary A path traversal vulnerability existed in the File component's tar archive extraction functionality. An authenticated user could upload a specially crafted tar archive containing symbolic links to read arbitrary files accessible to the application process. The vulnerability allowed an...

joserfc: HS256/HS384/HS512 verify accepts empty/nil HMAC key (cross-language sibling of CVE-2026-45363)

Summary joserfc.jwt.decode accepts attacker-forged HMAC-signed tokens when the caller-supplied verification key is the empty string or None. HMACAlgorithm.sign and HMACAlgorithm.verify in src/joserfc/rfc7518/jwsalgs.py:62-70 feed whatever OctKey.getopkey... produced into hmac.new..., and...

Inadequate Encryption Strength

Overview Affected versions of this package are vulnerable to Inadequate Encryption Strength in the verify process. An attacker can gain unauthorized access and forge arbitrary claims by submitting tokens signed with an empty or null key, which are incorrectly accepted as valid signatures. This is...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the public web-client endpoint for partial ZIP downloads of a browsable share. An attacker can access files outside the intended shared directory by supplying crafted file entries whose canonical paths begin with...

GHSA-H5GX-45RJ-2H5J Kerberos Hub private key (X-Kerberos-Hub-PrivateKey) leaked to cross-host redirect target due to redirect-following HTTP client without CheckRedirect

Summary The Kerberos Hub upload path sends the agent's Hub credentials in the custom X-Kerberos-Hub-PrivateKey and X-Kerberos-Hub-PublicKey request headers to the operator-configured Hub URL config.HubURI. The HTTP client used &http.Client in UploadKerberosHub is constructed without a CheckRedire...
