CVE-2026-108577: Konstanty Bialkowski libmodplug ABC Music Format load_abc.cpp abc_add_gchord resource consumption
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: 0.28% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- Fixed version: libmodplug (openSUSE:Leap 16.0) 0.8.9.0+git20170610.f6dd59a-bp160.2.1; libmodplug (openSUSE:Tumbleweed) 0.8.9.0+git20170610.f6dd59a-4.1.
- Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 2.1.
Low priority for now. Upgrade to libmodplug (openSUSE:Leap 16.0) 0.8.9.0+git20170610.f6dd59a-bp160.2.1; libmodplug (openSUSE:Tumbleweed) 0.8.9.0+git20170610.f6dd59a-4.1 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
A vulnerability was determined in Konstanty Bialkowski libmodplug up to 0.8.9.1. This issue affects the function abc_add_gchord of the file src/load_abc.cpp of the component ABC Music Format Parser. This manipulation causes resource consumption. The attack may be initiated remotely. The vendor was contacted early about this disclosure but did not respond in any way.
