CVE-2025-23386: gerbera: Privilege escalation from user gerbera to root because of insecure %post script

HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: gerbera (openSUSE:Tumbleweed) 2.5.0-1.1.

Low priority for now. Upgrade to gerbera (openSUSE:Tumbleweed) 2.5.0-1.1 or later.
