Improper neutralisation of delimiters in the pattern
input (specifically the command separator ;
and command substitution characters (
and )
) mean that arbitrary command injection is possible by modification of the input value used in a workflow. This has the potential for exposure or exfiltration of sensitive information from the workflow runner, such as might be achieved by sending environment variables to an external entity.
As of this writing, the issue has been patched for versions in the v1.x.x
release series in release v1.6.12
(also tagged as v1.6
and v1
). The latest available release v2.0.0
also includes a corresponding patch (also tagged as v2.0
and v2
).
Users should upgrade to at least the patched version v1.6.12
or preferably the latest available version v2.0.0
. Workflows that use the action ref v1
will automatically receive the patched version v1.6.12
in future workflow runs.
Patch summary:
Release series | Patched tags | Patched commit hashes |

Is it recommended that users update to the patched version v1.6.12
or the latest release version v2.0.0
, however remediation may be possible through careful control of workflows and the pattern
input value used by this action.
