Unauthenticated PHP Object Injection in Agora <= 1.9 versions.
AnalysisAI
PHP Object Injection in the Agora WordPress theme (by AncoraThemes) affects all versions up to and including 1.9, allowing remote unauthenticated attackers to inject serialized PHP objects that are deserialized by the application. Because exploitation requires no authentication and no user interaction over the network, a successful attack can lead to full compromise (arbitrary code execution, data theft, or site takeover) when a suitable gadget chain is present in the theme or its plugin ecosystem. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to be running the Agora WordPress theme version 1.9 or earlier and to expose the vulnerable code path that deserializes attacker-supplied input; per CVSS AV:N/AC:L/PR:N/UI:N this is reachable remotely without authentication or user interaction against default installations. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are largely aligned toward high severity but with an important caveat. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a crafted HTTP request to a public page of a WordPress site running the Agora theme (≤1.9), placing a serialized PHP object in a parameter that the theme passes to unserialize(). If a POP gadget chain exists among the site's loaded code, the injected object triggers sensitive magic-method behavior on deserialization - for example writing a webshell or executing code - resulting in site compromise. … |
| Remediation | No vendor-released patch version is identified in the available data, so the primary recommendation is to consult the Patchstack advisory (https://patchstack.com/database/wordpress/theme/agora/vulnerability/wordpress-agora-theme-1-9-php-object-injection-vulnerability) and the AncoraThemes vendor channel for an updated release above 1.9, then upgrade as soon as a fixed build is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Scan all WordPress installations to identify those using Agora theme by AncoraThemes versions 1.9 and below, then immediately disable the theme or implement WAF rules to block requests containing serialized PHP object patterns. …
