## What is CVE-2026-24403?

CVE-2026-24403 is a high-severity vulnerability in Color Iccdev, published on 24 Jan 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

iccDEV provides libraries and tools for interacting with, manipulating, and applying ICC color management profiles. In versions 2.3.1.1 and below, an integer overflow vulnerability exists in icValidateStatus CIccProfile::CheckHeader() when user-controllable input is incorporated into profile data unsafely. Tampering with tag tables, offsets, or size fields can trigger parsing errors, memory corruption, or DoS, potentially enabling arbitrary Code Execution or bypassing application logic. This issue has been fixed in version 2.3.1.2.

Weakness: CWE-20 (Improper Input Validation), CWE-190 (Integer Overflow or Wraparound)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-24403 and fix it if it is affected.

What it is: CVE-2026-24403 is a high-severity vulnerability in Color Iccdev, published on 24 Jan 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-24403 in the wild and no public exploit code.

Affected product: Color Iccdev. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
