CVE-2026-41470: LIVE555 < 2026.04.22 RTSP Server Authorization Bypass via Session Token

LIVE555 before 2026.04.22 contains an authorization bypass vulnerability in RTSP session command handling that allows attackers to replay valid Session tokens from unauthenticated connections. Attackers who obtain a valid Session token can issue PLAY and TEARDOWN commands from a second TCP connection without authentication, causing server crashes through virtual function call errors or disrupting active streams by terminating victim sessions.

Security readout for executives and security teams

Plain-English summary

LIVE555 RTSP servers before 2026.04.22 can accept a reused valid session token from another unauthenticated connection. An attacker who obtains such a token could disrupt streaming or crash the server. This is primarily an availability and operational continuity risk.

Executive priority

Prioritize remediation for internet-accessible or business-critical streaming services. The main impact is service disruption, not data theft, but outages may affect monitoring, media delivery, or operational visibility.

Technical view

The flaw is an authorization bypass in RTSP session command handling. Replayed Session tokens can authorize PLAY and TEARDOWN over a second TCP connection without authentication, potentially causing virtual function call errors or terminating another client’s stream.

Likely exposure

Exposure is most likely where LIVE555 RTSP server code before 2026.04.22 is directly deployed or embedded in products reachable over a network.

Exploitation context

The bundle includes public technical and exploit-labeled material, but CISA KEV is false and no source states active exploitation. Attackers must first obtain a valid Session token, matching the high attack complexity rating.

Researcher notes

Evidence supports CWE-863 authorization bypass and availability impact. Affected scope is stated as LIVE555 before 2026.04.22; downstream embedded products are not enumerated in the bundle and should be verified separately.

Mitigation direction

  • Upgrade LIVE555 to 2026.04.22 or later where applicable.
  • Check vendor guidance for products embedding LIVE555.
  • Restrict RTSP service access to trusted networks.
  • Require authentication and session isolation where supported.
  • Monitor for unusual PLAY, TEARDOWN, crashes, or stream interruptions.

Validation and detection

  • Inventory systems and products using LIVE555 RTSP server code.
  • Confirm deployed LIVE555 versions are 2026.04.22 or later.
  • Review vendor advisories for embedded LIVE555 dependencies.
  • Check logs for cross-connection session reuse indicators.
  • Verify RTSP exposure is limited to approved networks.

Incorrect Authorization

Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
