Descripción técnica

Backstage is an open framework for building developer portals. From 0.3.0 until 0.6.15 and 0.7.5, the @backstage/plugin-auth-node package did not consistently honor explicit negative email verification during shared OAuth profile normalization. The affected paths include a selected profile email marked verified: false, a matching raw provider email marked email_verified: false, and an email obtained only from an ID token marked email_verified: false. Exploitation requires an admitted identity-provider user who can supply or change an unverified email and a deployment that uses the selected profile email to resolve catalog identities. The verification metadata must apply to the selected email; an absent email_verified claim alone is not affected. In an affected configuration, the user may assume another catalog identity and obtain its associated access and permissions. This issue is fixed in versions 0.6.15 and 0.7.5.

——6Lotus through 0.10.2 contains an improper authentication vulnerability in the Go event ingestion middleware that validates API keys by prefix only, without checking the secret against the stored hashed_key. Attackers who know or obtain an API key prefix can submit usage events to POST /api/track/ as that organization, altering its metered usage and billing.1d CVE-2026-1119587.5 ALT

——2The Royal MCP WordPress plugin before 1.5.7 does not limit a preview-link token to the single preview it was issued for, so any party that obtains a valid token is authenticated as the token's owning user, an administrator in the default configuration, across the entire REST API with no nonce, leading to full site takeover.1d CVE-2026-1142226.2 MED

——7Traefik 2.11.0 before 2.11.58 and 3.0.0 before 3.7.14 contains an authentication bypass because a first request preauthenticated with an Authorization: Negotiate token authenticates a socket in the globally shared backend connection pool, which is never isolated. Unauthenticated attackers on separate frontend connections can be assigned that NTLM/Kerberos-bound socket and perform reads or writes with the victim's identity.23h CVE-2026-1146388.7 ALT

——2Traefik v3.7.0 before v3.7.14 contains an improper authentication vulnerability in the Kubernetes Ingress NGINX provider that merges client CAs when auth-tls-secret names collide after dot-to-dash normalization. Attackers holding certificates from another host's CA can access a host requiring its own client CA, while that host's legitimate clients are refused.23h CVE-2026-1144397.3 ALT
