Summary
CVE-2026-2110 is a medium-severity Improper Restriction of Excessive Authentication Attempts (CWE-307) vulnerability in Swiftbuy Swiftbuy. Its CVSS base score is 6.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 50th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-10 (Concurrent Session Control) and AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

CVE-2026-2110 is a vulnerability involving improper restriction of excessive authentication attempts in Tasin1025 SwiftBuy up to commit hash 0f5011372e8d1d7edfd642d57d721c9fadc54ec7. The flaw affects an unknown functionality within the /login.php file, enabling manipulation that bypasses limits on repeated login attempts. This issue, linked to CWE-307 (Improper Restriction of Excessive Authentication Attempts) and CWE-799 (Improper Control of Interaction Frequency), carries a CVSS v3.1 base score of 3.7 (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) and was published on 2026-02-07.
Remote attackers with network access and no privileges can exploit this vulnerability, though it requires high attack complexity and is rated as difficult to execute. Successful exploitation allows limited disclosure of confidential information (C:L) with no impact on integrity or availability, likely facilitating brute-force attacks against login credentials due to the lack of authentication attempt throttling.
Advisories from VulDB (ctiid.344686, id.344686, submit.746251) and WebSecurityInsights detail the issue, noting that an exploit has been publicly released and may be used in attacks. The product uses a rolling release model, providing no specific version details for affected or patched releases. The vendor was contacted early but provided no response, leaving no official patches or mitigations documented in the references.

Mitigating Controls (NIST 800-53 r5) AI
AC-7 directly enforces limits on consecutive failed logons, structurally blocking brute-force exploitation of the weakness.
ac-10 enforces a hard limit on concurrent sessions per user, directly stopping uncontrolled interaction frequency at the session level.
sc-5 reduces the impact of excessive request volume (DoS) but does not itself impose the frequency controls whose absence defines the weakness.
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.
Authentication enforcement directly includes lockout, throttling, and MFA policies that prevent brute-force attempts.
Behavioral monitoring of authentication activity can detect excessive failed attempts after they occur.
Protecting networks from unauthorized usage can incorporate rate limiting to bound interaction frequency.
Generating auth logs enables later detection or forensics but does not itself restrict attempts.
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.
Network security controls can enforce rate limiting and throttling at the perimeter.
Application security requirements explicitly include controls on interaction frequency and throttling.
Secure architecture principles recommend rate-limiting and resource-management mechanisms.
Secure coding practices can embed input-frequency and throttling checks in code.
CAPTCHA, account lock-out after repeated failures, and alerts on excessive attempts directly stop automated brute-force guessing of credentials.
Capacity management directly limits request rates and resource exhaustion that CWE-799 describes.
