Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly remediates the CSRF vulnerability in SunbirdEd-portal v1.13.4 through timely identification, reporting, and patching of the specific flaw.

SC-23 Session Authenticity good match

prevent

Requires session authenticity mechanisms like CSRF tokens to verify that requests originate from legitimate user interactions and prevent forged cross-site requests.

SI-10 Information Input Validation good match

prevent

Enforces validation of information inputs, including anti-CSRF tokens, to block unauthorized actions triggered by malicious cross-site requests.

Deeper analysisAI

CVE-2025-70031 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, discovered in Sunbird-Ed SunbirdEd-portal version 1.13.4. Published on 2026-03-09, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), reflecting its high severity due to network accessibility, low attack complexity, and potential for significant impacts.

An unauthenticated attacker (PR:N) can exploit this vulnerability remotely over the network (AV:N) by tricking a user into interacting with a malicious site or resource (UI:R), such as clicking a crafted link. With low complexity (AC:L) and unchanged scope (S:U), successful exploitation enables the attacker to perform unauthorized actions on the victim's behalf within the SunbirdEd-portal, resulting in high confidentiality, integrity, and availability impacts (C:H/I:H/A:H).
