Deserialization of Untrusted Data vulnerability in Elated-Themes Aperitif allows Object Injection.
This issue affects Aperitif: from n/a through 1.6.
AnalysisAI
Object injection in the Elated-Themes Aperitif WordPress theme through version 1.6 allows remote attackers to trigger PHP deserialization of attacker-controlled data, potentially leading to code execution, file manipulation, or full site compromise when a suitable gadget chain is present. CVSS 8.1 reflects high impact across confidentiality, integrity, and availability, though attack complexity is rated High. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires a WordPress site running the Elated-Themes Aperitif theme at version 1.6 or earlier with the vulnerable code path reachable over HTTP/HTTPS; the theme must be installed and active (or its vulnerable PHP file directly callable). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS:3.1 vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H indicates network-reachable, unauthenticated exploitation with no user interaction, but High attack complexity - consistent with object-injection bugs that require a viable gadget chain in the surrounding PHP environment to achieve meaningful impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A remote, unauthenticated attacker submits an HTTP request to a vulnerable Aperitif-powered WordPress site containing a crafted serialized PHP payload in a parameter, cookie, or option value that the theme passes to unserialize(). When PHP rehydrates the payload, magic methods on attacker-chosen classes from WordPress core or installed plugins fire (a POP chain), enabling arbitrary file write, SQL execution, or remote code execution and resulting in full site takeover. … |
| Remediation | No vendor-released patched version is identified in the available data - the advisory states the issue affects Aperitif 'from n/a through 1.6' without naming a fixed release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Scan all WordPress environments to identify Aperitif theme installations version 1.6 or earlier and classify by business criticality. …
