Summary

CVE-2026-2108 is a medium-severity Improper Resource Shutdown or Release (CWE-404) vulnerability in Jsbroks Coco Annotator. Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 50th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-2108 is a denial-of-service vulnerability in jsbroks COCO Annotator versions up to 0.11.1. It affects an unknown function within the /api/info/long_task endpoint of the component. The issue, classified as CWE-404, has a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) and was published on 2026-02-07.

Unauthenticated remote attackers can exploit this vulnerability with low attack complexity and no user interaction. By manipulating the endpoint, attackers can initiate a task queue flood, resulting in low-impact availability disruption through denial of service.

Advisories from VulDB and a GitHub vulnerability research disclosure indicate that the exploit has been publicly released and may be utilized. The vendor was contacted early regarding the issue but provided no response, and no patches or mitigations are detailed in the references.

Notable context includes the public availability of the exploit, increasing the risk for exposed instances of COCO Annotator.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect resource releases after code is written.

Engineering principles can require explicit resource acquisition/release patterns that stop improper shutdown from being introduced.

Priority-based resource allocation limits the blast radius when released resources are not returned to the pool.
