Package	Ecosystem	Affected	Fixed in
github.com/openbao/openbao	Go	<0.0.0-20260714163218-90272575e5f5 \|\| >=0.1.0, <=1.1.5	0.0.0-20260714163218-90272575e5f5

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

OpenBao (Go module github.com/openbao/openbao) versions from 0.1.0 through 1.1.5, plus certain pseudo-version builds, are affected. When OpenBao Agent's exec rendering mode hits certain error conditions, typically after num_retries is reached, it writes secrets listed in env_template to stdout. The source does not say what local or remote access is needed to read that output. The fix is in pseudo-version 0.0.0-20260714163218-90272575e5f5, and the advisory also names OpenBao v2.6.0 as the patched release, so upgrade to one of those.
