Exploitation Conditions

Requires the Arraytics Booktics plugin to be installed and active on a WordPress site at any version from the initial release through 1.0.29, and the attacker must reach the specific plugin request handler that passes user input into an SQL query. The advisory does not name the exact vulnerable parameter or endpoint, so the concrete injectable input is not identified in the available data. The CVSS vector asserts no authentication (PR:N) and no user interaction, but authentication requirements are not confirmed from the description text alone; defenders should verify with the vendor whether a login (e.g. subscriber-level) is actually needed, as this materially changes exposure. Limiting factors: the niche plugin must be present, and only sites running vulnerable versions are affected.

Impact

This is a network-exploitable SQL injection (CWE-89) in the Booktics WordPress plugin, scored CVSS 9.3 with vector AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L - low attack complexity, no privileges, no user interaction, and a changed scope reaching the backend database. On raw CVSS this reads as a high-priority issue. However, the corroborating exploitation signals are weak or absent: no EPSS score was provided, the CVE is NOT in CISA KEV, and no public proof-of-concept is referenced - so there is no public exploit identified at time of analysis and no evidence of active exploitation. The only intelligence source is a single Patchstack advisory (the reporter), with no NVD-enriched CPE, no vendor advisory, and no independent confirmation of affected version boundaries beyond 'n/a through 1.0.29'. The vector claims PR:N (unauthenticated), but Patchstack-class WordPress plugin SQLi findings frequently require at least a low-privilege authenticated session, and the description contains no auth detail to confirm PR:N - treat the unauthenticated claim as vendor-asserted, not independently verified. Net assessment: a genuinely serious code-level flaw whose real-world risk is tempered by a niche product footprint and the absence of any exploitation or POC signal, so this is a patch-promptly item rather than an emergency on the scale the 9.3 alone would imply.

Exploit ScenarioDerived

A remote attacker sends a crafted HTTP request to a vulnerable Booktics plugin endpoint (e.g. a booking or query parameter) that is passed unsanitized into an SQL statement, injecting attacker-controlled SQL. Given AV:N/AC:L, this requires only network reachability to the WordPress site and no special timing or user interaction, allowing extraction of database contents such as user records and WordPress secrets. No public proof-of-concept is referenced, so exploitation would require the attacker to independently identify the injectable parameter.

AnalysisAIv1 – Oct 18, 2026

SQL injection in the Arraytics Booktics WordPress plugin, affecting sites running versions through 1.0.29, allows remote attackers to influence SQL queries and access or alter backend database data. The assessed CVSS vector indicates network reachability, no required privileges or user interaction, high confidentiality impact, low integrity impact, and no availability impact, although the advisory does not name the vulnerable endpoint or parameter and authentication requirements should be verified. No public exploit identified at time of analysis.

RemediationAI

No vendor-released patch is identified in the available intelligence; the advisory documents the issue through Booktics 1.0.29 and does not provide a fixed version. Until a patched release is available, consider deactivating the Booktics plugin if booking functionality can be temporarily sacrificed; this removes exposure but stops bookings. If the plugin must remain active, add WAF or virtual-patching rules to inspect requests to /wp-content/plugins/booktics/ for SQL metacharacters and injection patterns, accepting possible false positives and incomplete coverage because the exact vulnerable endpoint is not named. Reduce the WordPress database user's privileges to the minimum needed, avoiding FILE, DROP, and broad administrative grants, to limit what a successful injection can read or change, though this may break plugins that assume broader rights. Monitor web and database logs for anomalous SQL syntax or unexpected queries against WordPress tables. Consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/booktics/vulnerability/wordpress-booktics-plugin-1-0-29-sql-injection-vulnerability?_s_id=cve for updates and vendor guidance.

Technical ContextAI · show details

CVE-2026-109894 is a CWE-89 SQL injection issue in the Booktics WordPress plugin maintained by Arraytics. The flaw arises when user-controlled input reaches an SQL query without adequate neutralization, such as missing parameterized queries or insufficient escaping before string concatenation. Because the advisory does not identify the exact parameter or request handler, the concrete injectable input is not confirmed from the available data; the plugin must be installed and active on a WordPress site, and the attacker must reach the relevant handler that passes input into the query. The assessed CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N vector describes a network-reachable issue with no privileges or user interaction per the vector, scope unchanged, high confidentiality impact, low integrity impact, and no availability impact, suggesting data disclosure is the primary risk with limited ability to alter data depending on the query context. No CPE strings or additional technical references were supplied beyond the Patchstack advisory.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Arraytics Booktics booktics allows SQL Injection.This issue affects Booktics: from n/a through 1.0.29.

Executive ViewAI

Why It Matters

The Arraytics Booktics WordPress plugin, versions through 1.0.29, contains a critical SQL injection vulnerability that could allow unauthenticated remote attackers to access or modify sensitive backend database data. This poses a high risk of data confidentiality breaches and limited integrity tampering for organizations using the plugin, and with no vendor-released patch identified at time of analysis, leadership should prioritize interim mitigations and consider temporary disablement or virtual patching. No public exploit has been identified at time of analysis, but the critical severity and network-reachable nature warrant immediate attention.

Business Impact: High
Compensating Controls

No vendor patch available; implement virtual patching via WAF with SQL injection rules, temporarily disable the plugin if not essential, restrict access to wp-admin and database, enforce least privilege on database accounts, and enable database activity monitoring.
