AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Network, unauthenticated, no interaction, but full impact realistically depends on a usable POP gadget chain, warranting AC:H rather than the input's AC:L.

Unauthenticated PHP Object Injection in Advice <= 1.18.0 versions.
AnalysisAI
PHP Object Injection in the AncoraThemes 'Advice' WordPress theme (versions up to and including 1.18.0) lets unauthenticated remote attackers pass attacker-controlled serialized data into an unsafe PHP deserialization sink (CWE-502). Because a suitable POP (property-oriented programming) gadget chain in the theme or a co-installed plugin can then be triggered, this can escalate to arbitrary file operations, data disclosure, or remote code execution. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the site run the AncoraThemes 'Advice' theme at version 1.18.0 or earlier and that attacker-controlled serialized data reach the theme's unsafe deserialization sink over the network - no authentication and no user interaction are needed (PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are strong but partially incomplete. … 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 endpoint of a WordPress site running Advice ≤1.18.0, embedding a serialized PHP object in a parameter that the theme deserializes without authentication. If a compatible POP gadget chain exists among the site's active theme/plugins, the injected object triggers file writes, data exfiltration, or code execution during object teardown. … |
| Remediation | No vendor-released patched version is identified in the provided data (the advisory establishes 1.18.0 and below as vulnerable but names no fixed release), so consult the Patchstack advisory (https://patchstack.com/database/wordpress/theme/advice/vulnerability/wordpress-advice-theme-1-18-0-php-object-injection-vulnerability?_s_id=cve) and the AncoraThemes vendor page for an update above 1.18.0 and apply it once available. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all WordPress installations using AncoraThemes 'Advice' theme version 1.18.0 or earlier, immediately deactivate the affected theme across all instances, and isolate any systems unable to be remediated from production network access. …
