## What is CVE-2024-45412?

CVE-2024-45412 is a medium-severity denial of service vulnerability in yeti-platform yeti, published on 10 Sep 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Yeti bridges the gap between CTI and DFIR practitioners by providing a Forensics Intelligence platform and pipeline. Remote user-controlled data tags can reach a Unicode normalization with a compatibility form NFKD. Under Windows, such normalization is costly in resources and may lead to denial of service with attacks such as One Million Unicode payload. This can get worse with the use of special Unicode characters like U+2100 (℀), or U+2105 (℅) which could lead the payload size to be tripled. Versions prior to 2.1.11 are affected by this vulnerability. The patch is included in 2.1.11.

Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling)

Check this codebase for CVE-2024-45412 and fix it if it is affected.

What it is: CVE-2024-45412 is a medium-severity denial of service vulnerability in yeti-platform yeti, published on 10 Sep 2024. 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-2024-45412 in the wild and no public exploit code.

Affected product: yeti-platform yeti. 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.
