CVE-2026-41605: Apache Thrift: Swift Compact Protocol integer overflow

Integer Overflow or Wraparound vulnerability in Apache Thrift. This issue affects Apache Thrift: before 0.23.0. Users are recommended to upgrade to version 0.23.0, which fixes the issue.

Security readout for executives and security teams

Plain-English summary

Apache Thrift versions before 0.23.0 contain an integer-overflow flaw in the Swift Compact Protocol. A remote, unauthenticated attacker may be able to cause serious confidentiality and availability impacts, although exploitation is rated high complexity. Organizations using affected Thrift components should upgrade promptly.

Executive priority

Prioritize remediation as high for internet-facing or untrusted-input services. The potential business consequences include data exposure, service disruption, and limited data modification. Upgrade during the nearest expedited maintenance window, while validating whether the affected protocol is actually reachable.

Technical view

CVE-2026-41605 is a CWE-190 integer overflow or wraparound in Apache Thrift's Swift Compact Protocol. CVSS 3.1 scores it 7.7: network-accessible, unauthenticated, requiring no user interaction, with high attack complexity, high confidentiality and availability impact, and low integrity impact. Versions before 0.23.0 are affected.

Likely exposure

Exposure is likely where Apache Thrift earlier than 0.23.0 is present and the affected Swift Compact Protocol is reachable through network-facing or upstream-controlled data. The sources do not identify specific applications, configurations, or request paths required to trigger the flaw, so asset-level reachability must be established locally.

Exploitation context

The supplied record is not listed in KEV, and the sources provide no evidence of active exploitation or public weaponization. The CVSS vector indicates remote, unauthenticated exploitation is possible but requires high attack complexity. Treat exposed affected services seriously without assuming exploitation has occurred.

Researcher notes

The public bundle establishes the weakness class, affected version boundary, fixed release, and CVSS characteristics, but does not describe the precise overflow location, triggering conditions, affected Swift APIs, or observed indicators. Testing should remain defensive and focus on dependency identification, protocol reachability, version verification, and post-upgrade regression coverage.

Mitigation direction

  • Upgrade Apache Thrift to version 0.23.0 or later.
  • Apply applicable Red Hat security errata for downstream packaged deployments.
  • Prioritize network-reachable services processing untrusted Thrift traffic.
  • Consult Apache and distribution guidance for deployment-specific remediation details.

Validation and detection

  • Inventory applications and dependencies containing Apache Thrift.
  • Confirm every deployed Thrift version is 0.23.0 or later.
  • Identify whether affected services use the Swift Compact Protocol.
  • Determine whether untrusted network input can reach affected Thrift processing.
  • Verify applicable Red Hat packages include the relevant security errata.
