Lack of authentication when using the "snapshot diff" functions in qSnapper before version 1.3.3 allowed a local attacker to see otherwise read protected information.
AnalysisAI
Unauthenticated local access to qSnapper's D-Bus snapshot diff interface before version 1.3.3 exposes read-protected file contents to any local user on the host. The 'snapshot diff' D-Bus methods - GetFileChanges, GetFileChangesBetween, GetFileDiffBetween, and GetFileDiffAndDetails - lacked any Polkit authorization check, meaning a local unprivileged caller could invoke them directly and receive sensitive file diff data. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local user session on a host where qSnapper before 1.3.3 is installed and its D-Bus service is running. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 with vector AV:L/AC:L/AT:N/PR:N/UI:N/VC:H accurately characterizes this as a medium-severity local information disclosure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local unprivileged user on a Linux host running qSnapper before 1.3.3 uses a D-Bus client tool (e.g., dbus-send or gdbus) to directly invoke GetFileDiffBetween with two snapshot identifiers, receiving a full file diff in return without any authentication prompt appearing. The returned diff may include contents of files protected by filesystem ACLs that the calling user cannot read directly. … |
| Remediation | Vendor-released patch: qSnapper 1.3.3, available at https://github.com/presire/qSnapper/releases/tag/v1.3.3. … Detailed patch versions, workarounds, and compensating controls in full report. |
