## What is CVE-2024-50633?

CVE-2024-50633 is a vulnerability in CERN Indico, published on 16 Jan 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A Broken Object Level Authorization (BOLA) vulnerability in Indico through 3.3.5 allows attackers to read information by sending a crafted POST request to the component /api/principals. NOTE: this is disputed by the Supplier because the product intentionally lets all users retrieve certain information about other user accounts (this functionality is, in the current design, not restricted to any privileged roles such as event organizer).

Weakness: CWE-201 (Insertion of Sensitive Information Into Sent Data)

Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-50633 exists.

Affected packages and fixed versions:
- indico (PyPI): affected from 3.2.9; fixed in 3.3.3
- indico (PyPI): affected from 3.2.9; fixed in 3.3.3
- indico (PyPI): affected from 3.2.9; fixed in 3.3.3

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.
