CVE-2024-13787
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe VEDA - MultiPurpose WordPress Theme theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.2 via deserialization of untrusted input in the 'veda_backup_and_restore_action' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe VEDA WordPress theme (versions up to 4.2) contains a PHP Object Injection vulnerability in the 'veda_backup_and_restore_action' function, which deserializes untrusted input. Authenticated attackers with Subscriber-level access can inject arbitrary PHP objects. While no POP chain exists in the theme itself, the presence of any other plugin or theme containing a POP chain on the same WordPress installation enables full remote code execution, arbitrary file deletion, or data exfiltration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm VEDA theme is installedNavigate to Appearance > Themes in WordPress admin panel and check if the VEDA theme is installed. Also check if it is the active theme.Affected if VEDA theme is installed and active on the WordPress site
-
Check VEDA theme versionInspect the style.css file in the theme directory (wp-content/themes/veda/) and look for the 'Version:' header, or check the theme version displayed in the WordPress admin theme list.Affected if The installed version matches the vulnerable version range (verify against official VEDA theme release notes for patch status)
-
Verify vulnerable function existsCheck if the file containing 'veda_backup_and_restore_action' function exists in the theme. Search for this function name in the theme's PHP files, typically in includes or functions directories.Affected if The function 'veda_backup_and_restore_action' is present in the theme code
-
Check for subscriber-level user accountsReview WordPress user roles in Users > All Users and identify any accounts with Subscriber-level access. These accounts can trigger the vulnerable function.Affected if Any Subscriber-level user accounts exist on the WordPress site
-
Assess POP chain potentialAudit installed plugins and themes for known PHP Object Injection POP chains. Review active plugins against known vulnerabilities that could be chained with this flaw.Affected if Other installed plugins or themes contain exploitable POP chains that could be triggered via this vulnerability
A site is affected if VEDA theme is installed with the vulnerable function present AND an attacker can obtain Subscriber-level access, with exploitation severity dependent on available POP chains in other plugins or themes.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate the VEDA theme to a patched version once available. Until then, disable the vulnerable function via theme code removal or access control, and audit the WordPress installation for other plugins/themes that may provide a POP chain.
VEDA theme version 4.3 or later
- Check the current version of the VEDA theme installed on your WordPress site by navigating to Appearance > Themes in the WordPress admin dashboard
- Update the VEDA theme to version 4.3 or later, which contains the fix for the PHP Object Injection vulnerability
- After updating, verify the new version is correctly installed by checking the theme details in Appearance > Themes
- If version 4.3 is not available from the theme provider, contact the theme developer (ThemeForest) directly to request the patched version
- Review installed plugins and themes for any that contain POP chains (serialization unserialize() calls) that could be exploited in conjunction with this vulnerability, and ensure all other software is also up to date
