CVE-2026-19658

CriticalCVSS 9.8
Published: Translated: NVD NIST

Summary

The Give Tributes plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.3.1 via deserialization of untrusted input. Unauthenticated attackers can inject a PHP Object, but the vulnerability has no impact unless another plugin or theme containing a POP chain is installed. Exploitation requires the "Allow Multiple Recipients" option to be enabled and the eCard "Custom Message" option to be disabled (the plugin default).

Risk Assessment

If additional plugins or themes with a POP chain are installed in the WordPress environment, an attacker could delete files, retrieve sensitive data, or execute code. The risk is limited when no such POP chain exists.

Recommendation

Update the Give Tributes plugin to a version newer than 2.3.1 once available, and review installed plugins and themes for known POP chains.

Original NVD description (English source)

The Give Tributes plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.3.1 via deserialization of untrusted input . This makes it possible for unauthenticated attackers 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. This vulnerability is only reachable when the "Allow Multiple Recipients" option is enabled for the donation form, as the single-recipient code path applies sanitize_textarea_field() which would neutralize the payload. Exploitation additionally requires the eCard "Custom Message" option to be disabled, which is the plugin default: when it is enabled the personalized message becomes a required field and GiveWP's give_clean() blanks serialized input during validation, causing the donation to be rejected before it is stored.
