Vulnerability from osv_openeuler – Published: 2025-10-17 11:09 – Updated: 2026-08-06 11:09 – Source website

Summary

cjson security update

Details

cJSON aims to be the dumbest possible parser that you can get your job done with. It's a single file of C, and a single header file. %package devel Summary: Development files for cJSON Requires: = - %description devel The cjson-devel package contains libraries and header files for developing applications that use cJSON. %prep %autosetup -n cJSON- -p1

Security Fix(es):

cJSON 1.5.0 through 1.7.18 allows out-of-bounds access via the decode_array_index_from_pointer function in cJSON_Utils.c, allowing remote attackers to bypass array bounds checking and access restricted data via malformed JSON pointer strings containing alphanumeric characters.(CVE-2025-57052)

Severity

9.8 (Critical)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
