CVE-2025-41118: Pyroscope is an open-source continuous profiling database.

Pyroscope is an open-source continuous profiling database.

Pyroscope is an open-source continuous profiling database. The database supports various storage backends, including Tencent Cloud Object Storage (COS). If the database is configured to use Tencent COS as the storage backend, an attacker could extract the secret_key configuration value from the Pyroscope API. To exploit this vulnerability, an attacker needs direct access to the Pyroscope API. We highly recommend limiting the public internet exposure of all our databases, such that they are only accessible by trusted users or internal systems. This vulnerability is fixed in versions: 1.15.x: 1.15.2 and above. 1.16.x: 1.16.1 and above. 1.17.x: 1.17.0 and above (i.e. all versions). Thanks to Théo Cusnir for reporting this vulnerability to us via our bug bounty program.

What it means for a small business

If your business uses Pyroscope, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.41%, higher than 34% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 28, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
