Echo: jq: security update to 1.7.1-6+deb13u1+e2

high Tenable Self-Hosted Container Security Plugin ID 464586

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used
 MurmurHash3 with a hardcoded, publicly visible seed (0x432A9843) for all JSON object hash table
 operations, which allowed an attacker to precompute key collisions offline. By supplying a crafted JSON
 object (~100 KB) where all keys hashed to the same bucket, hash table lookups degraded from O(1) to O(n),
 turning any jq expression into an O(n²) operation and causing significant CPU exhaustion. This affected
 common jq use cases such as CI/CD pipelines, web services, and data processing scripts, and was far more
 practical to exploit than existing heap overflow issues since it required only a small payload. This issue
 has been patched in commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784. (CVE-2026-40164)

Solution

Update the jq library and its related packages to version 1.7.1-6+deb13u1+e2 or later.
