Summary
The SponsorMe plugin for WordPress up to version 0.5.2 is vulnerable to Reflected Cross-Site Scripting via the PHP_SELF parameter. Insufficient input sanitization and output escaping allow unauthenticated attackers to inject arbitrary web scripts that execute if a user clicks a crafted link.
Risk Assessment
An attacker can hijack an administrator or user session, steal data, or perform other malicious actions in the victim's context.
Recommendation
Immediately update the SponsorMe plugin to the latest available version and follow general security practices such as avoiding clicking on suspicious links.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
- CVE-2026-124490Critical
OpenEMR before 8.3.0 contains a path traversal vulnerability in the RingCentral RCFaxClient disposeDocument() method of oe-module-faxsms that allows authenticated attackers to read and write arbitrary files via the file_path parameter. Attackers can use action=download to read credentials and source code, or action=setup with base64 content to write web-executable files for code execution.
- CVE-2026-124469Critical
OpenEMR before 8.3.0 contains an SQL injection vulnerability in the Fee Sheet drug-inventory lookup (DrugSalesService::sellDrug) that interpolates the prod[N][warehouse] POST field into an ORDER BY clause. Low-privileged authenticated users can submit Fee Sheet product lines with constant subqueries to run a time-based blind oracle, extracting patient data and users_secure bcrypt hashes.
- CVE-2026-124450Critical
OpenEMR before 8.3.0 contains a broken access control and path traversal vulnerability in the fax/sms module disposeDocument action via an unvalidated file_path parameter. Authenticated low-privilege users can read sqlconf.php to recover database credentials and write arbitrary files as the web user, enabling remote code execution.
- CVE-2026-124445Critical
OpenEMR from 7.0.1 before 8.4.0 contains a flaw in src/Common/Auth/OneTimeAuth.php that ignores the enforce_onetime_use and max_access_count flags, never revokes consumed service_auth tokens, and checks login_pin without rate limiting or strict comparison. Attackers holding a captured token can replay it or brute-force the PIN to open patient-portal sessions exposing PHI.
- CVE-2026-124440Critical
Kyverno from 1.19.1 before 1.19.2 contains an authorization bypass vulnerability in the apiCall namespace clamp that allows namespace tenants to issue cross-namespace and cluster-scoped API requests by appending malformed percent-escapes to urlPath. Attackers can create namespaced Policies whose apiCall runs as the admission-controller ServiceAccount to read other namespaces' resources and create mutating webhooks, escalating to cluster admin.
- CVE-2026-124427Critical
Craft CMS from 5.0.0 before 5.11.2 contains an authorization bypass vulnerability that allows anonymous GraphQL clients to read out-of-scope section entries via prev/next fields. Attackers can chain next hops from one visible in-scope entry to enumerate entries and read titles, slugs, and custom-field content from withheld sections.
- CVE-2026-123614Critical
imgproxy from 4.0.0 before 4.0.16 contains an integer overflow in the ICO loader that allows remote attackers to trigger a heap buffer overflow via a crafted data_size value. Attackers can submit a crafted ICO image whose data_size wraps the allocation in vips/icoload.c, corrupting heap memory to crash the process or achieve code execution.
- CVE-2026-123551Critical
OpenAM from 14.0.0 before 16.1.4 contains an information disclosure vulnerability that allows unauthenticated attackers to read live session tokens from the notification WebSocket. Attackers can bypass the agent-only check through an unvalidated internal forward on legacy Liberty ID-FF endpoints, collecting iPlanetDirectoryPro tokens to hijack user and administrator sessions.
Original NVD description (English source)
The SponsorMe plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via PHP_SELF Parameter in all versions up to, and including, 0.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The PHP_SELF value is reflected in two separate locations within the vulnerable function — a form action attribute and an anchor href attribute — both of which can be exploited by appending a crafted payload to the wp-admin/admin.php URL path.
