CVE-2026-32316
Multiple security issues were discovered in jq, a command-line JSON processor, which could result in denial of service or potentially the execution of arbitrary code when processing untrusted input. This update additionally addresses three issues for which no CVE has been assigned: GHSA-ggc9-rpv2-xgpm, GHSA-gvwx-xj9r-3frq and GHSA-gf4g-95wj-4q4r. Two changes in behaviour follow from the fixes above. An operation whose result would exceed the internal string length limit, such as repeating or escaping a very large string, now terminates with the error "String too long" instead of returning a truncated result. A comparison or containment check on a deeply nested value now reports an error rather than recursing until the stack is exhausted. Filters relying on the previous behaviour will report an error where they previously appeared to succeed. https://security-tracker.debian.org/tracker/DSA-6416-1
