Descrição técnica

GraphQL Tools provides utilities for building, stitching, and mocking GraphQL schemas. Prior to version 1.1.36 of the GraphQL Tools legacy WebSocket executor package, buildWSLegacyExecutor in packages/executors/legacy-ws/src/index.ts retains request.extensions.connectionParams in the closure-scoped executorConnectionParams object after cleanupWebsocket closes a connection. When one executor is reused across different authorization contexts, a later request that omits a sensitive key can send an earlier caller's Authorization or tenant value in its connection_init payload, causing the downstream server to authenticate the later caller as the earlier user. Applications that create a new executor for every request are not affected. This issue is fixed in version 1.1.36 of the GraphQL Tools legacy WebSocket executor package.

———The validating recursor in Hickory DNS hickory-recursor 0.25.0 through 0.26.0-alpha.1, hickory-resolver 0.26.0-alpha.1 before 0.26.2, and hickory-net 0.26.0-beta.1 before 0.26.2 caches DNSSEC-bogus answers using the untrusted, attacker-supplied record TTL (capped at 24 hours) instead of a short validation-failure TTL. A remote attacker who spoofs a single authoritative response with an invalid signature and a long TTL can keep the bogus result cached for up to 24 hours.9h CVE-2026-1235973.7 BAI

—

———Hickory DNS hickory-proto 0.25.0-alpha.1 through 0.26.0-alpha.1 and hickory-net before 0.26.2 contain a logic bug in DnssecDnsHandle's DS-fetch path that caches transient DS lookup errors as Bogus DNSSEC validation verdicts. An attacker who induces a SERVFAIL, REFUSED, or timeout response to a child-zone DS sub-query causes the validator to return SERVFAIL for all names under that zone until the cache entry's TTL expires.9h CVE-2026-1235286.8 MÉD

—

———Vikunja before 2.7.1 contains an insufficient session expiration vulnerability that allows holders of revoked access tokens to keep authenticating because SetupTokenMiddleware skips session and account-status checks. Attackers with a stolen token can, after logout, password reset, or account disabling, mint OAuth sessions via /oauth/authorize or tk_ API tokens for persistent access.9h CVE-2026-1234935.4 MÉD

—

———Vikunja from 2.4.0 before 2.7.1 contains an authentication bypass vulnerability that allows disabled or locked users to retain access through API tokens owned by their bot users. Because token validation only checks the bot's own status, attackers holding pre-minted bot tokens can keep reading and modifying shared projects via the HTTP API, CalDAV, MCP and feeds.9h CVE-2026-669863.3 BAI

——0HCL AION is affected by a vulnerability where user sessions did not expire after a sufficient period of inactivity. An unattended authenticated session could be used by another person with access to the same system to view information or perform actions on behalf of the user, potentially resulting in unintended behavior or security impact under certain conditions.2d CVE-2026-84155—

——1CodeChecker's web server fails to fully invalidate a session token on logout when the server runs with more than one API worker process (the default). Each worker process maintains its own in-memory session cache; logout only clears the cache of the single worker that handles the request (plus the shared database record). Other workers continue to honor the destroyed token from their stale in-memory copies until the session's lifetime expires. An attacker who has captured a valid token can therefore keep impersonating the user after the user has logged out.2d
