Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, Jervis uses padLeft(32, '0') when it should use padLeft(64, '0') because SHA-256 produces 32 bytes which equates to 64 hex characters. This vulnerability is fixed in 2.2.

 https://cve.radiocsirt.org/vuln/ghsa-67rj-pjg6-pq59 GHSA-67rj-pjg6-pq59 — Jervis Has a SHA-256 Hex String Padding Bug 2026-10-06T05:49:03.748203+00:00

Affected: Maven: net.gleske:jervis

### Vulnerability

https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L622-L626

`padLeft(32, '0')` should be `padLeft(64, '0')`. SHA-256 produces 32 bytes = 64 hex characters.

### Impact

* Inconsistent hash lengths when leading bytes are zero * Comparison failures for hashes with leading zeros * Potential security issues in hash-based comparisons * Could cause subtle bugs in systems relying on consistent hash lengths

Severity is considered low for internal uses of this library but if there's any consumer using these methods directly then this is considered high.

### Patches

Upgrade to Jervis 2.2.

### Workarounds

Use an alternate SHA-256 hash function or upgrade.
