CVE-2023-46646: Improper access control in all versions of GitHub Enterprise Server allows unauthorized users to view private repository names via the "Get
Noroxi assessment
Priority: Monitor (action score 21/100)
- 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: 0.54% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: GitHub Enterprise Server 3.10.4, 3.7.19, 3.8.12.
Low priority for now. Upgrade to GitHub Enterprise Server 3.10.4, 3.7.19, 3.8.12 or later.
