## What is CVE-2022-21549?

CVE-2022-21549 is a medium-severity unsafe deserialization vulnerability in Debian Debian Linux, published on 19 Jul 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 17.0.3.1; Oracle GraalVM Enterprise Edition: 21.3.2 and 22.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 5.3 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

Weakness: CWE-502 (Deserialization of Untrusted Data)

Check this codebase for CVE-2022-21549 and fix it if it is affected.

What it is: CVE-2022-21549 is a medium-severity unsafe deserialization vulnerability in Debian Debian Linux, published on 19 Jul 2022. 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-2022-21549 in the wild and no public exploit code.

Affected packages and fixed versions:
- java (Bitnami): affected from 12.0.0; fixed in 17.0.4
- java-min (Bitnami): affected from 12.0.0; fixed in 17.0.4
- jre (Bitnami): affected from 12.0.0; fixed in 17.0.4

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.
