Missing backport observation: CVE-2026-24779 on releases/v0.9.0

Upstream main carries the fix for CVE-2026-24779 (replaces urllib.urlparse with urllib3.util.parse_url, hardening URL parsing). The releases/v0.9.0 branch appears to lack it.

Statusbranch is behind main and the introduced symbol/imports are not yet present

If releases/v0.9.0 is still a supported maintenance line, a cherry-pick (or note that the branch will not receive this class of fix) would help downstream consumers track exposure.

extent analysis

TL;DR

Cherry-pick the upstream commit that fixes CVE-2026-24779 into the releases/v0.9.0 branch to address the missing security patch.

Guidance

  • Verify the absence of the fix in the releases/v0.9.0 branch by checking for the presence of from urllib3.util import parse_url in vllm/connections.py.
  • Cherry-pick the commit f46d576c54 from the upstream main branch into releases/v0.9.0 to apply the security fix.
  • Confirm that the branch is still a supported maintenance line before applying the fix.
  • After applying the fix, verify that the urllib3.util.parse_url import is present in vllm/connections.py at the branch HEAD.

Notes

The provided information implies that the fix is available in the upstream main branch, but it is unclear if the releases/v0.9.0 branch is still actively maintained.

Recommendation

Apply workaround: Cherry-pick the upstream commit into the releases/v0.9.0 branch to ensure downstream consumers can track and mitigate exposure to CVE-2026-24779.
