## What is CVE-2026-24012?

CVE-2026-24012 is a high-severity denial of service vulnerability in Apache IoTDB, published on 6 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Uncontrolled Resource Consumption vulnerability in Apache IoTDB. 

Some interface fails to impose reasonable
limits on the time span and aggregation interval of the query. An attacker
can construct a request with extreme parameters (e.g., a very large time
range combined with a minimal interval). This forces the DataNode to build
an enormous result set in memory, which exhausts the Java heap and causes
the DataNode process to crash.

This issue affects Apache IoTDB: from 1.3.3 before 2.0.8.

Users are recommended to upgrade to version 2.0.8, which fixes the issue.

Weakness: CWE-400 (Uncontrolled Resource Consumption)

## Which versions are affected by CVE-2026-24012?

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-24012 and fix it if it is affected.

What it is: CVE-2026-24012 is a high-severity denial of service vulnerability in Apache IoTDB, published on 6 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-2026-24012 in the wild and no public exploit code.

Affected packages and fixed versions:
- apache-iotdb (PyPI): affected from 1.3.3; fixed in 2.0.8

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.
