CVE-2026-115398: Ghidra before 12.2 Denial of Service via TAR and ZIP File System Mount

MediumCVSS 6.8 · v4.0—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

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

Ghidra before 12.2 contains a resource allocation without limits vulnerability in FileSystemIndexHelper used by TarFileSystem and ZipFileSystem, which store unbounded archive entries. Attackers can persuade a user to open or batch-import a crafted TAR or ZIP archive with excessive entries to exhaust the Java heap and hang the session.
