Bazel 9 End of Life Date
Bazel 9 end-of-life date, support status, and CVE risk. Data from endoflife.date and official vendor documentation.
Bazel 9 was released on January 20, 2026 and support is scheduled to end on December 31, 2028 — a planned supported lifespan of 3 years, in line with the 3 years median for Bazel LTS releases. It is a long-term support (LTS) release, so it carries a longer patch window than the interim releases around it. Its most recent patch is 9.2.0, published July 13, 2026.
What does Bazel 9 end of life mean?
When Bazel 9 reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: Most vulnerability scanners check for known CVEs but do not flag the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Running Bazel 9 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to Bazel 9 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
