Published by the GitHub Advisory Database at 27 May 2026, 19:58 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `github.com/crowdsecurity/crowdsec` (Go): affected `>=1.5.0, <1.7.8`; fixed in `1.7.8`

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> CrowdSec AppSec versions from 1.5.0 up to but not including 1.7.8 fail to read request bodies for requests with chunked transfer encoding or HTTP/2 requests without a content-length header, so body-inspection WAF rules silently never match. An unauthenticated remote attacker can send such a request with a malicious body and have it forwarded as allowed, without a WAF log entry. Upgrade the Go module github.com/crowdsecurity/crowdsec to version 1.7.8. The source lists no complete workaround.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-rw47-hm26-6wr7>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
