Echo: cjson: security update to 1.7.18-3.1+deb13u1+e2

medium Tenable Cloud Security Plugin ID 472792

Description

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

 - cJSON through 1.7.19 applies RFC 6902 JSON Patch operations non-atomically in apply_patch() in
 cJSON_Utils.c. For a replace operation that is missing its value member, or a move operation whose
 destination path cannot be resolved, the existing target member is detached and deleted before the
 operation is fully validated, so the target document is mutated while cJSONUtils_ApplyPatches() or
 cJSONUtils_ApplyPatchesCaseSensitive() returns a failure status. An attacker who can supply the patch
 document can destroy addressable members of the target document even though the API reports that the patch
 failed, defeating the all-or-nothing behavior callers rely on to reject bad patches. (CVE-2026-67217)

Solution

Update the cjson library and its related packages to version 1.7.18-3.1+deb13u1+e2 or later.
