CVE-2025-49618
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:NSummary
CVE-2025-49618 is a medium-severity Resource Leak (CWE-402) vulnerability in Linkedin (inferred from references). Its CVSS base score is 5.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 28th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

V3.5.8
Mitigating Controls (NIST 800-53 r5) AI
Explicitly enforces information-flow rules that block private resources from reaching unauthorized external spheres.
Enforces approved authorizations so private resources cannot be transmitted outside their intended sphere.
Boundary controls monitor and restrict communications that would otherwise leak private resources.
Requires confidentiality protection on transmitted data, directly stopping exposure of private resources.
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.
Enforcing least-privilege access permissions directly prevents private resources from being exposed outside their intended sphere.
Logical segmentation and unauthorized-access protections stop resources from leaking into untrusted domains.
Encryption of data-at-rest reduces the value of any leaked resource but does not address the transmission flaw itself.
Protecting data-in-transit mitigates exposure during movement yet does not prevent the underlying boundary violation.
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.
Information-access-restriction directly prevents private resources from being exposed beyond intended boundaries.
Access-control mechanisms limit who can receive resources that should remain internal.
Managing access rights helps ensure resources are not granted to untrusted parties.
Data-leakage-prevention technologies specifically block unintended transmission of sensitive resources.
Information-transfer rules can prevent unintended disclosure of private resources outside the product.
Network-security controls can limit exposure paths but do not address the root resource-leak logic.
