CVE-2025-49825: Teleport allows remote authentication bypass

CriticalCVSS 9.8 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Plan (action score 41/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 7.9% (FIRST EPSS); higher than 94.8% of all records.
  • 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.com/gravitational/teleport (Go) 12.4.35, 13.4.27, 14.4.1; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20250730T213748-1.1; teleport (openSUSE:Tumbleweed) 17.5.3-1.1.

Add it to your regular patch cycle. Upgrade to github.com/gravitational/teleport (Go) 12.4.35, 13.4.27, 14.4.1; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20250730T213748-1.1; teleport (openSUSE:Tumbleweed) 17.5.3-1.1 or later.
