CVE-2026-41048: CWE-863: Incorrect Authorization in presire qSnapper
Incorrect caching of authentication between different polkit methods in qSnapper before version 1.3.3 allowed a local attacker to use functions like "restore from snapshot" even if only allowed to do "delete snapshot".
AI Analysis
Technical Summary
CVE-2026-41048 is an authorization bypass vulnerability in presire qSnapper prior to version 1.3.3. The issue arises from incorrect caching of authentication states between different polkit methods, enabling a local attacker with limited permissions (e.g., allowed to delete snapshots) to invoke higher-privilege functions such as restoring snapshots. This flaw violates proper authorization checks, potentially allowing unauthorized snapshot restoration.
Potential Impact
A local attacker with permission to delete snapshots can exploit this vulnerability to restore snapshots, an action they are not authorized to perform. This could lead to unauthorized system state changes or rollback, impacting system integrity. The CVSS 4.0 score of 8.4 reflects high impact on confidentiality and integrity with low attack complexity and no user interaction required.
Mitigation Recommendations
No official patch or remediation level is currently confirmed. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users only to mitigate exploitation risk.
