CVE-2026-104982: Path Traversal in Linux Mint Xreader
A path traversal vulnerability exists in Linux Mint Xreader versions 4.6.0 through 4.6.5 in the EPUB File Handler component. This flaw allows remote attackers to manipulate file paths via the setup_document_content_list/g_strdup_printf function, potentially accessing unauthorized files. The issue is addressed by upgrading to version 4.6.6. Additionally, EPUB support has been removed from Xreader and reimplemented in a separate project called Xepub.

Technical Summary
CVE-2026-104982 is a path traversal vulnerability in Linux Mint Xreader affecting versions 4.6.0 through 4.6.5. The flaw resides in the setup_document_content_list/g_strdup_printf function within the backend/epub/epub-document.c file of the EPUB File Handler component. This vulnerability allows remote attackers to manipulate file paths, potentially leading to unauthorized file access. The vulnerability has been fixed in version 4.6.6. The project maintainer notes that EPUB support was removed from Xreader and reimplemented in Xepub.
Potential Impact
The vulnerability allows remote attackers to perform path traversal attacks, potentially accessing files outside the intended directory structure. This could lead to unauthorized disclosure of sensitive information. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low complexity, no privileges required, and user interaction needed with limited confidentiality impact.
Mitigation Recommendations
Upgrade Linux Mint Xreader to version 4.6.6 or later to remediate this vulnerability. Note that EPUB support has been removed from Xreader and is now provided by the separate Xepub project. No other mitigation is required as the fix is available.
