Summary
CVE-2026-74880 is a critical-severity Use of HTTP Request With Sensitive Query String (CWE-598) vulnerability in Jahlives Openssl Encrypt. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 45th 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 SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

V14.2.1
Mitigating Controls (NIST 800-53 r5) AI
Requiring confidentiality and integrity protection for transmitted data reduces exposure of sensitive query parameters even though the control does not forbid placing secrets in URLs.

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.
HTTPS encryption protects query strings in transit but does not address the root design flaw of placing sensitive data in URLs.
Secure SDLC practices directly prevent embedding sensitive data in query strings as part of input-handling and data-flow design.

Network security controls can enforce HTTPS and block sensitive data in URLs.
A.8.26 only requires that security requirements (including those that could address query-string exposure) be identified and specified during development; it does not itself enforce, implement or stop exploitation of sensitive data in the query string
Secure architecture principles discourage exposing sensitive data in URLs.
Secure coding standards directly prohibit placing secrets in query parameters.
Security testing can detect sensitive data leakage via query strings.
