CVE-2026-123508: Vikunja before 2.7.1 Supply Chain Risk via Unpinned xgo Release Toolchain

Noroxi assessment

Priority: Monitor (action score 8/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.09% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. Special conditions such as timing or configuration are required.
  • Fixed version: go-vikunja vikunja 2.7.1.

Low priority for now. Upgrade to go-vikunja vikunja 2.7.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Vikunja before 2.7.1 contains a supply chain vulnerability in its mage release targets that fetch the xgo module and Docker image by mutable latest references. Attackers who compromise the upstream xgo module, image, or registry can inject malicious code into subsequently built release binaries shipped under a valid signature.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
