AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network-reachable deserialization with no user interaction gives AV:N/AC:L/PR:N/UI:N; a viable POP chain yields full C:H/I:H/A:H, though realistic impact is gadget-dependent.

Unauthenticated PHP Object Injection in Abogado <= 1.18 versions.
AnalysisAI
Unauthenticated PHP Object Injection in the Abogado WordPress theme (by AncoraThemes) affects all versions up to and including 1.18, allowing remote attackers to inject crafted serialized PHP objects without authentication. If a suitable POP (property-oriented programming) gadget chain is present in the theme, its bundled plugins, or WordPress core, this can escalate to arbitrary file operations, SQL injection, or remote code execution. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires reaching the theme code path that deserializes untrusted input; per CVSS PR:N/UI:N this is unauthenticated and needs no user interaction, so any Abogado ≤1.18 site exposed to the internet is in scope by default. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:H, base 9.8) presents this as maximally severe - network-reachable, low complexity, no authentication or user interaction, full CIA impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A remote, unauthenticated attacker sends an HTTP request to the vulnerable Abogado endpoint containing a crafted serialized PHP object in a parameter that reaches unserialize(). PHP reconstructs the object, and via magic methods a POP gadget chain from the theme, an active plugin, or WordPress core is triggered - potentially writing a webshell, reading wp-config.php, or executing code. … |
| Remediation | No vendor-released patch identified at time of analysis - the input specifies only affected versions (≤1.18) and no fixed release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WordPress installations to identify those running Abogado theme version 1.18 or earlier; deactivate the theme immediately on any affected sites to block exploitation. …
