- **Severity:** Medium 6.5 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N`)
- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Over the internet
- **Victim action needed:** Not needed

- **Published:** 11 Feb 2025
- **Updated:** 14 Jul 2026
- **Also known as:** CLSA-2026-1781274016, DEBIAN-CVE-2022-37660, GHSA-hmq6-3hm7-3h78, UBUNTU-CVE-2022-37660

## What is CVE-2022-37660?

CVE-2022-37660 is a medium-severity vulnerability in n/a, published on 11 Feb 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association. An attacker that successfully bootstrapped public keys with another entity using PKEX in the past, will be able to subvert a future bootstrapping by passively observing public keys, re-using the encrypting element Qi and subtracting it from the captured message M (X = M - Qi). This will result in the public ephemeral key X; the only element required to subvert the PKEX association.

Weakness: CWE-323 (Reusing a Nonce, Key Pair in Encryption)

Check this codebase for CVE-2022-37660 and fix it if it is affected.

What it is: CVE-2022-37660 is a medium-severity vulnerability in n/a, published on 11 Feb 2025. 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-2022-37660 in the wild and no public exploit code.

Affected product: n/a. 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.
