# CVE-2024-42360: Command Injection in sequenceserver

**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 0.6% , percentile 47: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 47% of all scored CVEs (low). 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 sequenceserver (RubyGems) < 3.1.2, fixed in 3.1.2 . Check your lockfile, including transitive dependencies.

## What it is

SequenceServer lets you rapidly set up a BLAST+ server with an intuitive user interface for personal or group use. Several HTTP endpoints did not properly sanitize user input and/or query parameters. This could be exploited to inject and run unwanted shell commands. This vulnerability has been fixed in 3.1.2.

## Affected packages

- RubyGems `sequenceserver` < 3.1.2 → fixed: 3.1.2

## Affected products (CVE record)

- wurmlab sequenceserver: < 3.1.2

## Severity

- GitHub_M CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.58% probability of exploitation activity in the next 30 days; percentile 47.
