Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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).

Mitigating Controls (NIST 800-53 r5) AI
Access enforcement requires verifying that state-changing requests originate from the authenticated user rather than a forged cross-site source.
Protecting session authenticity prevents attackers from replaying or forging authenticated requests via the victim's browser.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require anti-CSRF controls such as tokens or SameSite attributes.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
By denying access to phishing or malicious sites, the control lowers the likelihood that a user will be tricked into submitting a forged request that performs an unintended action on another site.
Contextual intelligence about emerging CSRF toolkits can be translated into updated anti-CSRF token or same-site policy configurations across applications.
