SCA: security update for github.com/gittuf/gittuf (GHSA-vxvc-cg7j-rwqj)

medium Tenable Cloud Security Plugin ID 441452

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - gittuf is a platform-agnostic Git security system. Prior to 0.14.0, an attacker with push access to
 gittuf's Reference State Log (RSL) can roll back the current policy to any previous policy trusted by the
 current set of root keys. gittuf determines the policy to load by inspecting the RSL. Except for the very
 first policy (which is automatically trusted given gittuf's TOFU model, or verified against manually
 specified keys), whenever an RSL entry that points to a new policy is encountered, gittuf validates that
 this policy is trusted. This is done by checking that the new policy’s root metadata is signed by the
 required threshold of the current policy's root keys. Because of this, an attacker with push access to the
 RSL may create a new entry that references an old policy (that is trusted by the most recent policy's set
 of root keys), thereby rolling back gittuf's policy to the attacker's chosen state. This vulnerability is
 fixed in 0.14.0. (CVE-2026-44544)

Solution

Update the github.com/gittuf/gittuf library and its related packages to version 0.14.0 or later.
