Summary

CVE-2025-15688 is an unauthenticated SQL Injection vulnerability affecting the Capella WordPress theme, developed by ThemeGoods, in versions 2.5.5 and earlier. The flaw allows a remote, unauthenticated attacker to inject and execute arbitrary SQL commands against the site’s database. It carries a CVSS v3.1 base score of 9.3 (Critical).

Technical details

  • Root cause: Improper neutralization of special elements used in an SQL command (CWE-89) within the Capella theme’s code, allowing user-supplied input to be incorporated into SQL queries without adequate sanitization or parameterization.
  • Trigger conditions: No authentication or user interaction is required to exploit the flaw.
  • Attack vector: Network-based (AV:N) — an attacker can send crafted requests directly to the affected WordPress site over the web.
  • Impact: Successful exploitation yields high confidentiality impact (unauthorized read access to database contents, e.g., extraction of user credentials or sensitive site data) and low availability impact, with no direct integrity impact per the published vector.

Affected software

  • ThemeGoods Capella WordPress theme — all versions up to and including 2.5.5

Severity

  • CVSS v3.1 Base Score: 9.3 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L

Mitigation and recommended actions

  • Immediate: Upgrade the Capella theme to a version newer than 2.5.5 as soon as the vendor releases a patched build.
  • If no patch is yet available: Restrict or monitor direct external access to the WordPress site, deploy a Web Application Firewall (WAF) with SQL injection detection/blocking rules in front of the site, and review database and web server logs for anomalous query patterns indicative of injection attempts. Consider taking the theme offline or switching to an alternative theme until a fix is confirmed.

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.
