Summary

CVE-2026-24744 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Invoiceplane Invoiceplane. Its CVSS base score is 5.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked at the 12th 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 SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

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

CVE-2026-24744 is a Stored Cross-Site Scripting (XSS) vulnerability, classified under CWE-79, affecting InvoicePlane version 1.7.0, a self-hosted open source application for managing invoices, clients, and payments. The flaw occurs in the Edit Invoices functions, where the application fails to validate user input in the `invoice_number` parameter, enabling the injection of malicious scripts. Published on 2026-02-18, it carries a CVSS v3.1 base score of 5.7 (AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:H/A:L).

Exploitation requires administrator privileges, allowing a malicious admin to inject XSS payloads via the vulnerable parameter. Successful attacks can lead to unauthorized modification of application data, creation of persistent backdoors through stored malicious scripts, and full compromise of the application's integrity, particularly when combined with user interaction from other admins or users viewing affected invoices.

InvoicePlane version 1.7.1 patches the issue by addressing the input validation deficiency. Security practitioners should review the fixing commit at https://github.com/InvoicePlane/InvoicePlane/commit/93622f2df88a860d89bfee56012cabb2942061d6 and the GitHub security advisory at https://github.com/InvoicePlane/InvoicePlane/security/advisories/GHSA-5mxx-553h-m62w for implementation details and upgrade guidance.

the `invoice_number` parameter. Although administrator privileges are required to exploit it, this is still considered a critical vulnerability as it can cause actions such as unauthorized modification of application data, creation of persistent backdoors through stored malicious scripts, and full compromise of the application's integrity. Version 1.7.1 patches the issue.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover missing or incorrect input neutralization through targeted web-application tests.

SI-10 Information Input Validation good match

Input validation directly enforces neutralization of untrusted data before it reaches web output generation.

SI-15 Information Output Filtering good match

Output filtering can catch or sanitize unneutralized script content before it is served to users.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).

PR.PS-02 partial match
prevents

Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).

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

Secure-coding testing and automated code-analysis tools are applied to detect improper neutralization of script-related content during web-page generation.

A.5.6 Contact with special interest groups partial match
prevents

Knowledge exchange on emerging attack techniques and patches reduces the likelihood that cross-site scripting flaws remain unaddressed in deployed applications.

A.5.7 Threat intelligence partial match
prevents

Operational indicators of compromise for web-application attacks can be incorporated into WAF or input-filtering rules, lowering the likelihood that unsanitized data reaches the browser.

A.8.25 Secure development life cycle partial match
prevents

Requiring language-specific secure-coding standards and automated scanning during the SDLC catches missing output encoding or improper neutralization of untrusted data before the software reaches production.

A.8.28 Secure coding partial match
prevents

Secure-coding standards, SAST scans and removal of insecure code samples together eliminate the failure to neutralize script content that produces cross-site scripting flaws.
