CVE-2026-56207: CWE-347 Improper Verification of Cryptographic Signature in Apache Software Foundation Apache Impala
Signature of Bearer token is not verified in last step of SAML2 authentication for Impala's hs2-http interface, allowing altering user name and acting as another user. This issue affects Apache Impala: >=4.0.0. Users are recommended to upgrade to version 4.5.2, which fixes this issue.
AI Analysis
Technical Summary
This vulnerability (CWE-347) in Apache Impala affects versions starting from 4.0.0. The problem lies in the improper verification of the cryptographic signature of the Bearer token during the last step of SAML2 authentication on the hs2-http interface. Because the signature is not verified, an attacker can modify the user name in the token and act as another user. The vendor recommends upgrading to version 4.5.2 to remediate this issue.
Potential Impact
An attacker exploiting this vulnerability can impersonate other users by altering the user name in the Bearer token without proper signature verification. This could lead to unauthorized access and potential privilege escalation within systems relying on Apache Impala's hs2-http interface for authentication.
Mitigation Recommendations
Users should upgrade Apache Impala to version 4.5.2, which addresses this vulnerability by properly verifying the Bearer token signature during SAML2 authentication. Patch status is not explicitly confirmed beyond this recommendation; check the vendor advisory for the latest remediation guidance.
