Summary

CVE-2025-55155 is a medium-severity Insertion of Sensitive Information Into Sent Data (CWE-201) vulnerability in Mantisbt Mantisbt. Its CVSS base score is 5.4 (Medium).

Operationally, ranked at the 5th 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 SI-10 (Information Input Validation) and SI-15 (Information Output Filtering) — see the control section below for these in your framework.

Vulnerability Data

Mantis Bug Tracker (MantisBT) is an open source issue tracker. In versions 2.27.1 and below, when a user edits their profile to change their e-mail address, the system saves it without validating that it actually belongs to the user. This…

could result in storing an invalid email address, preventing the user from receiving system notifications. Notifications sent to another person's email address could lead to information disclosure. This issue is fixed in version 2.27.2.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of email address inputs during profile updates to ensure the address is owned by and reachable for the user before acceptance.

prevent

Requires filtering of outbound notifications so they are only sent to verified addresses, preventing disclosure to unintended recipients.

prevent

Enforces information flow rules that restrict system notifications from being transmitted to unverified or unauthorized email addresses.

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.DS-01 mostly match
prevents

Requires cryptographic hashes and signatures that directly enforce integrity-check validation for data at rest.

PR.DS-02 mostly match
prevents

Requires cryptographic hashes and signatures that directly enforce integrity-check validation for data in transit.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent insertion of sensitive data into application outputs and messages.

DE.CM-09 partial match
prevents

Monitoring runtime data flows and outputs can detect sensitive data being transmitted.

ID.RA-09 partial match
prevents

Mandates pre-acquisition integrity assessment, addressing only the initial portion of the weakness lifecycle.

PR.DS-10 partial match
prevents

Protecting data-in-use includes removing confidential values before they are processed or sent.

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.

prevents

Data-masking techniques can prevent sensitive values from appearing in transmitted payloads.

prevents

Cryptographic controls mandate integrity mechanisms whose correct validation directly prevents CWE-354.

prevents

Secure coding standards require proper implementation and validation of checksums or MACs.

detects

Security testing can detect missing integrity validation but does not itself implement the control.

mitigates

Classification identifies sensitive data so it is not inadvertently transmitted.

mitigates

Labelling makes sensitive data visible to developers and prevents accidental inclusion in outbound messages.
