MediumCVSS 5.4Exploitation Probability (EPSS)
Low risk7th percentile - higher than 7% of all known CVEs
Summary
The My Login WordPress plugin before 7.2.0 does not enforce the network's registration setting when processing site signups on multisite installations, allowing users with a subscriber account, and unauthenticated users on some networks, to create new sites and be granted administrator over them.
Risk Assessment
Unauthorized users can create new sites and gain full control over them, potentially leading to network resource takeover, malicious content distribution, or privilege escalation.
Recommendation
Update the My Login plugin to version 7.2.0 or later which includes the fix. Additionally, review multisite registration settings and restrict site creation to trusted users only.

IBM WebSphere Extreme Scale versions 8.6.1.0 through 8.6.2.2 have an improper Content Security Policy configuration that could allow a remote attacker to bypass security restrictions. The flaw concerns browser-side protection mechanisms.
- 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.
