CVE-2024-5858 is a vulnerability classified under CWE-862 (Missing Authorization) found in the quantumcloud AI Infographic Maker plugin for WordPress. The issue stems from the absence of a capability check on the AJAX action 'qcld_openai_title_generate_desc', which is responsible for generating or updating post titles via AI assistance. Because this authorization check is missing, any authenticated user with at least Subscriber-level privileges can invoke this AJAX endpoint to modify arbitrary post titles on the affected WordPress site. This vulnerability affects all versions of the plugin up to and including 4.7.4. The flaw does not require user interaction beyond authentication and can be exploited remotely over the network. The impact is limited to integrity, as attackers can alter post titles, potentially misleading site visitors or damaging content credibility. Confidentiality and availability are not affected. The CVSS v3.1 base score is 4.3, with vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, indicating network attack vector, low attack complexity, requiring privileges, no user interaction, unchanged scope, no confidentiality or availability impact, and limited integrity impact. No public exploits or patches have been reported at the time of publication, but the vulnerability is publicly disclosed and should be addressed promptly.

The primary impact of CVE-2024-5858 is the unauthorized modification of post titles on WordPress sites using the quantumcloud AI Infographic Maker plugin. This integrity compromise can lead to misinformation, brand damage, or manipulation of content presentation, which may affect user trust and site reputation. While it does not directly expose sensitive data or disrupt service availability, altered post titles can be used in social engineering or phishing campaigns by misleading site visitors. Since the vulnerability requires authenticated access at Subscriber level or higher, attackers must first gain some level of user access, which may be easier on sites with weak user management or where Subscriber accounts are common. The scope is limited to sites running this specific plugin, but given WordPress's widespread use, the potential attack surface is significant. Organizations relying on this plugin for content creation should consider the risk of content integrity loss and potential downstream effects on user trust and SEO rankings.

To mitigate CVE-2024-5858, organizations should first check for and apply any available updates or patches from quantumcloud addressing this authorization flaw. If no patch is available, administrators should consider temporarily disabling the AI Infographic Maker plugin or restricting its use to trusted users only. Implementing strict user role management to limit Subscriber-level accounts and monitoring for unusual post title changes can help detect exploitation attempts. Additionally, web application firewalls (WAFs) can be configured to block or alert on suspicious AJAX requests targeting 'qcld_openai_title_generate_desc'. Site owners should also audit user permissions regularly and enforce strong authentication mechanisms to reduce the risk of unauthorized access. Finally, monitoring site content integrity and setting up alerts for unexpected post title modifications can provide early warning of exploitation.
