Summary

CVE-2026-18550 is a critical privilege escalation vulnerability in the Nokri – Job Board WordPress Theme (developed by scriptsbundle) affecting all versions up to and including 1.6.6. The flaw resides in the theme’s password reset logic and allows a completely unauthenticated attacker to take over any user account, including administrators. It carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: the nokri_reset_password() function does not properly validate the password reset token supplied in the request against the token stored in the sb_password_forget_token user meta value.
  • Trigger condition: when a user has never requested a password reset (or the stored token is empty/unset), an attacker can submit an empty token value, which matches the empty/unset stored value and passes validation.
  • Attack vector: remote, over the network, via the theme’s password reset request handling — no authentication or user interaction required.
  • Impact: successful exploitation lets an attacker set a new password for any account, including administrator accounts, resulting in full account takeover and complete loss of confidentiality, integrity, and availability for the affected site.

Affected software

  • Nokri – Job Board WordPress Theme (vendor: scriptsbundle), all versions up to and including 1.6.6.

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: No patched version has been publicly confirmed at the time of writing. Site owners should monitor the vendor (scriptsbundle) for a fixed release of the Nokri theme and update immediately once available.
  • If no patch is available: disable or restrict access to the theme’s password reset functionality, monitor for suspicious password reset requests (particularly those with empty or missing tokens), enforce multi-factor authentication for administrator accounts, and consider taking the affected reset endpoint offline via a web application firewall rule until a fix is released.

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.
