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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly include coding standards for correct resource allocation and release.
Runtime monitoring can detect resource exhaustion caused by improper shutdown or release.
Lifecycle management of assets can encompass proper resource release at end-of-life or shutdown.
Capacity management helps surface leaks from unreleased resources but does not prevent the coding flaw.

Including restart, recovery and media-handling instructions reduces the likelihood that resources or sensitive data will be left in an exposed or improperly released state after a failure.
