CVE-2023-26123: 
NixOS vulnerability analysis and mitigation

CVE-2023-26123 is a Cross-site Scripting (XSS) vulnerability affecting versions of raysan5/raylib before 4.5.0. The vulnerability was discovered by Eugene Lim and disclosed on April 13, 2023. The issue specifically affects the SetClipboardText API when the library is compiled for PLATFORM_WEB, while other platforms (Desktop/Mobile/Embedded) remain unaffected (Snyk).

The vulnerability exists because the SetClipboardText API does not properly escape the single quote (') character, which allows attacker-controlled input to break out of the string and execute arbitrary JavaScript via the emscriptenrunscript function. The issue is classified as CWE-79 (Cross-site Scripting) and has been assigned a CVSS v3.1 score of 6.1 (medium severity) (Snyk).

When exploited, this vulnerability could allow attackers to execute arbitrary JavaScript code in the context of the web application using raylib. This could potentially lead to cookie theft, session hijacking, exposure of sensitive information, access to privileged services and functionality, or delivery of malware (Snyk).

The vulnerability has been fixed in raylib version 4.5.0. Users are advised to upgrade to this version or later to address the security issue. The fix includes implementing security checks to prevent malicious code execution through the SetClipboardText API (GitHub Release).
