CVE-2026-41048
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
In qSnapper before version 1.3.3, incorrect caching of authentication between different polkit methods allowed a local attacker to use functions like 'restore from snapshot' even if only allowed to do 'delete snapshot'.
Risk Assessment
The risk involves privilege escalation for a local user who can perform unauthorized system restore operations, potentially leading to data loss or system integrity compromise.
Recommendation
It is recommended to immediately update qSnapper to version 1.3.3 or later, which fixes this vulnerability. Also review polkit configuration to ensure proper permission separation.
Other vulnerabilities in qSnapper
See all- CVE-2026-41049High
Incorrect caching of authentication between different users in the qSnapper dbus service before version 1.3.3 allows any local attacker to use dbus functions after a privileged user has authenticated.
- CVE-2026-41047Medium
In qSnapper before version 1.3.3, lack of authentication in the "snapshot diff" functions allowed a local attacker to read otherwise read-protected information.
- CVE-2026-41046High
A path traversal vulnerability in qSnapper before version 1.3.3 allows a local attacker to use malicious snapper config files via the "configName" parameter. This can lead to denial of service or potential privilege escalation to root.
- CVE-2026-41045High
A time-to-check-time-of-use vulnerability in the polkit authentication of qSnapper before version 1.3.3 allowed a local attacker to bypass qSnapper's authentication mechanism and operate with root privileges.
