Summary

CVE-2026-65579 is an unauthenticated PHP Object Injection (deserialization of untrusted data, CWE-502) vulnerability in the Agricola WordPress theme by AxiomThemes. It affects Agricola versions up to and including 1.21.0 and carries a CVSS v3.1 base score of 9.8 (Critical). An unauthenticated, remote attacker can exploit it, potentially leading to full site compromise.

Technical details

  • Root cause: The theme deserializes untrusted, attacker-controllable data without proper validation (CWE-502), allowing injection of crafted PHP objects.
  • Trigger conditions: No authentication and no user interaction are required to reach the vulnerable code path.
  • Attack vector: Network — the flaw is remotely exploitable over HTTP(S) with low attack complexity.
  • Impact: Object injection can be leveraged against available PHP gadget chains, with high impact to confidentiality, integrity, and availability; consequences may include remote code execution and full site takeover.

Affected software

  • Agricola WordPress theme (AxiomThemes) — all versions up to and including 1.21.0.

Severity

  • CVSS v3.1 base score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Update the Agricola theme to a release later than 1.21.0 once available from the vendor.
  • If no patch is available: Restrict internet-facing access to the affected site, deploy a web application firewall to filter serialized-object payloads in requests, and monitor for anomalous requests targeting the theme. Remove or disable the theme if it is not required.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
