CVE-2025-49842: conda-forge-webservices Privilege Escalation Risk via Default Docker Root User

LowCVSS 1.0 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 4/100)

  • 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: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • Fixed version: conda-forge conda-forge-webservices 2025.3.24.

Low priority for now. Upgrade to conda-forge conda-forge-webservices 2025.3.24 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

conda-forge-webservices is the web app deployed to run conda-forge admin commands and linting. Prior to version 2025.3.24, the conda_forge_webservice Docker container executes commands without specifying a user. By default, Docker containers run as the root user, which increases the risk of privilege escalation and host compromise if a vulnerability is exploited. This issue has been patched in version 2025.3.24.
