# CVE-2024-33434: tiagorlampert CHAOS vulnerable to arbitrary code execution

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.4% , percentile 71: FIRST’s model estimates a 1.4% chance of exploitation activity in the next 30 days, higher than 71% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes github.com/tiagorlampert/CHAOS (Go) < 0.0.0-20220716132853-b47438d36e3a, fixed in 0.0.0-20220716132853-b47438d36e3a . Check your lockfile, including transitive dependencies.

## What it is

An issue in tiagorlampert CHAOS v5.0.1 before 1b451cf62582295b7225caf5a7b506f0bad56f6b and 24c9e109b5be34df7b2bce8368eae669c481ed5e allows a remote attacker to execute arbitrary code via the unsafe concatenation of the filename argument into the buildStr string without any sanitization or filtering.

## Affected packages

- Go `github.com/tiagorlampert/CHAOS` < 0.0.0-20220716132853-b47438d36e3a → fixed: 0.0.0-20220716132853-b47438d36e3a
