## What is CVE-2022-23625?

CVE-2022-23625 is a medium-severity denial of service vulnerability in wireapp wire-ios, published on 11 Mar 2022. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Wire-ios is a messaging application using the wire protocol on apple's ios platform. In versions prior to 3.95 malformed resource identifiers may render the iOS Wire Client completely unusable by causing it to repeatedly crash on launch. These malformed resource identifiers can be generated and sent between Wire users. The root cause lies in [wireapp/wire-ios-transport](https://github.com/wireapp/wire-ios-transport), where code responsible for removing sensible tokens before logging may fail and lead to a crash (Swift exception) of the application. This causes undesirable behavior, however the (greater) Wire system is still functional. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.

Weakness: CWE-755 (Improper Handling of Exceptional Conditions)

Check this codebase for CVE-2022-23625 and fix it if it is affected.

What it is: CVE-2022-23625 is a medium-severity denial of service vulnerability in wireapp wire-ios, published on 11 Mar 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-23625 in the wild and no public exploit code.

Affected product: wireapp wire-ios. 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.
