Overview<\/strong><\/p>\n

The CVE-2025-57317 vulnerability stems from a prototype pollution issue discovered in the apidoc-core, a core parser library. This vulnerability affects all versions up to 0.15.0. If successfully exploited, attackers can sabotage the system causing denial of service (DoS) or potentially compromising data. Owing to the widespread use of apidoc-core, this vulnerability can have significant impacts on numerous systems and applications.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-57317
\nSeverity: High (CVSS 7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Denial of Service (DoS), Possible System Compromise, and Data Leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

apidoc-core | versions up to and including 0.15.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

This vulnerability is exploited by an attacker sending a specially crafted payload, which injects properties on Object.prototype in the preProcess function of apidoc-core. The manipulated payload can cause prototype pollution, leading to a denial of service (DoS) condition, potential system compromise, and possible data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Potential exploitation of this vulnerability might look like the following pseudocode:<\/p>\n

POST \/parse HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"__proto__\": {\"crash\": true} }<\/code><\/pre>\n
In this example, the payload `{“__proto__”: {“crash”: true}}` is sent to the vulnerable endpoint (`\/parse`). This payload could lead to prototype pollution and cause a DoS condition or potentially compromise the system.<\/p>\n
Recommendation<\/strong><\/p>\n
The recommended mitigation against this vulnerability is to apply the vendor patch once it is available. If this is not possible immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Regularly updating and patching software is a fundamental part of maintaining cybersecurity and should be a priority for all systems using apidoc-core.<\/p>\n","protected":false},"excerpt":{"rendered":"
