# CVE-2026-14935: Security feature bypass in Red Hat Enterprise Linux 10

> Attackers can bypass WebRTC DTLS fingerprint validation by exploiting an inverted logic check, enabling man-in-the-middle attacks on media streams.

- **Severity:** Low 3.7 (`CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N`)
- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 7 Jul 2026
- **Updated:** 10 Sep 2026
- **Also known as:** DEBIAN-CVE-2026-14935, ECHO-a225-c93b-3c5d, GHSA-m678-vwg3-59mp, UBUNTU-CVE-2026-14935

## What is CVE-2026-14935?

CVE-2026-14935 is a low-severity vulnerability in Red Hat Enterprise Linux 10, published on 7 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A logic vulnerability was found in GStreamer's webrtcbin component. The _check_sdp_crypto() function contains an inverted boolean condition that causes it to accept remote SDP offers or answers that lack the required a=fingerprint attribute, while incorrectly rejecting those that include it. An attacker with the ability to intercept and modify WebRTC signaling messages could exploit this to bypass the SDP-level DTLS certificate fingerprint binding, weakening defenses against man-in-the-middle attacks on media streams.

Weakness: CWE-670 (Always-Incorrect Control Flow Implementation)

Check this codebase for CVE-2026-14935 and fix it if it is affected.

What it is: CVE-2026-14935 is a low-severity vulnerability in Red Hat Enterprise Linux 10, published on 7 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-14935 in the wild and no public exploit code.

Affected product: Red Hat Enterprise Linux 10. 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.
