Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

CA-8 Penetration Testing

addresses: CWE-79

Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.

SI-10 Information Input Validation

addresses: CWE-79

Validates web inputs to reject script-related content that could produce XSS.

SI-15 Information Output Filtering

addresses: CWE-79

Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1059.007 JavaScript Execution

Adversaries may abuse various implementations of JavaScript for execution.

attack.mitre.org →

T1185 Browser Session Hijacking Collection

Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.

T1539 Steal Web Session Cookie Credential Access

An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.

Why these techniques?

Stored XSS via unsanitized SVG upload directly enables exploitation of the network-accessible web app (T1190) to execute attacker-controlled JavaScript (T1059.007), facilitating browser session hijacking (T1185) and web session cookie theft (T1539) for data modification and persistent client-side backdoors.

NVD Description

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability occurs in the upload Login Logo functions of InvoicePlane version 1.7.0. In the Upload Login Logo, the application allows uploading svg…

files. 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.

Deeper analysisAI

CVE-2026-24745 is a Stored Cross-Site Scripting (XSS) vulnerability, tied to CWE-79, affecting the Upload Login Logo function in InvoicePlane version 1.7.0. InvoicePlane is a self-hosted open-source application designed for managing invoices, clients, and payments. The flaw stems from the application's allowance of SVG file uploads without adequate validation or sanitization, enabling the storage and execution of malicious scripts.

Exploitation requires administrator privileges (PR:H) and user interaction (UI:R), with network access (AV:N) and low attack complexity (AC:L). An authorized administrator can upload a malicious SVG file containing an XSS payload via the Login Logo upload feature. Successful exploitation enables unauthorized modification of application data, creation of persistent backdoors through stored scripts, and full compromise of the application's integrity, as reflected in the CVSS v3.1 base score of 5.7 (AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:H/A:L).

InvoicePlane version 1.7.1 addresses the vulnerability with a patch.
