Summary

CVE-2026-2627 is a high-severity Link Following (CWE-59) vulnerability. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 15th 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-6 (Least Privilege) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

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

CVE-2026-2627 is a security vulnerability in Softland FBackup versions up to 9.9, affecting an unknown function within the library C:\Program Files\Common Files\microsoft shared\ink\HID.dll of the Backup/Restore component. The flaw involves improper link following, corresponding to CWE-59 (Improper Link Resolution Before File Access ('Link Following')), and was published on 2026-02-17.

The vulnerability requires local access with low privileges (AV:L/PR:L), low attack complexity (AC:L), and no user interaction (UI:N), yielding a CVSS v3.1 base score of 7.8 (High) due to high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). A local attacker could manipulate the affected function to follow symbolic links, potentially leading to unauthorized file access, modification, or execution with elevated privileges.

VulDB advisories detail the issue and note that the vendor was contacted early for disclosure but provided no response. A proof-of-concept exploit is publicly available in the GitHub repository at https://github.com/thezdi/PoC/tree/main/FilesystemEoPs, which may enable real-world attacks.

The exploit has been released to the public, increasing the risk of exploitation on unpatched systems running vulnerable FBackup versions. No vendor patches or official mitigations are available.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Proper enforcement of access authorizations on the resolved target resource stops a link from reaching an unintended object.

AC-6 Least Privilege partial match

Least-privilege limits the damage an attacker can cause after following an unintended link.

SI-10 Information Input Validation partial match

Validating file-name inputs can reject or canonicalize names that resolve to links before access occurs.

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.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require code to validate paths and avoid unsafe link following.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect link-following flaws before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC practices can mandate link-resolution checks and canonicalization before file access.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly require safe handling of symbolic links and path traversal.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles include input validation and safe file-access design patterns.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address canonicalization and symlink attacks during implementation.

A.8.3 Information access restriction none match
mitigates

Access-control rules can limit which files are reachable, reducing exposure to malicious links.
