CVE-2026-45118 Aug 18, 15:55 CRITICAL PATCH Act Now

Reflected JavaScript injection and open redirect in MyBB forum software before 1.8.40 lets a remote attacker execute script in a victim's browser session. The Contact module (contact.php) takes a redirect target from the 'from' request parameter or the Referer header and passes it to redirect() without validating the URL scheme, so a javascript: URI can be delivered as the destination of the post-submission 'Click here if you don't want to wait any longer' link. CVSS is 9.3; no public exploit identified at time of analysis, and the flaw requires the victim to click the crafted link.

CVE-2026-49276 Jun 18, 15:04 PHP HIGH PATCH GHSA This Week

Cross-site scripting in Kirby CMS's Panel writer field (versions <= 4.9.3 and 5.0.0-alpha.1 through 5.4.3) lets an authenticated user inject a JavaScript-scheme URL into the link or email marks that executes in their own browser session when clicked before the content is saved. In Kirby's default configuration this is limited to self-XSS requiring social engineering, but Panel plugins that embed the <k-writer> component without sanitizing HTML before storage can be escalated to stored XSS affecting other users. There is no public exploit and it is not in CISA KEV; the vendor rates it high severity for affected sites.

Stored cross-site scripting in Django admin's URLField rendering allows a malicious URL value (e.g., using a `javascript:` scheme) to be displayed as a clickable link on changelist views and read-only admin fields without scheme validation. Any application that accepts URLField input via public-facing forms and exposes those records in the Django admin is affected, covering Django 5.2 through the 6.1 release candidate. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis; patches were released August 4, 2026 as Django 5.2.17 and 6.0.8.

CVE-2026-48591 Jun 17, 16:42 MEDIUM This Month

Stored cross-site scripting in earmark (the Elixir Markdown-to-HTML library by pragdave) allows any attacker who can submit markdown content to inject arbitrary JavaScript that executes in the browsers of users who view the rendered output. The root cause is a code path in `_make_att1/2` (`lib/earmark/transform.ex`) that splices HTML attribute values verbatim without encoding double-quote characters, enabling a crafted link URL or title to break out of the `href` attribute and inject additional HTML event handlers. Critically, no patched version will be released - the library has been officially retired from Hex - making migration to a maintained alternative the only complete fix. No public exploit identified at time of analysis, though the CVE description itself contains a working proof-of-concept payload.

Stored cross-site scripting in OpenClaw's session HTML export feature allows unsafe javascript: and data: URI schemes to survive into generated output files. All OpenClaw versions before 2026.5.12 are affected; exploitation requires a trusted operator to open an exported session HTML file and actively click a crafted link, at which point arbitrary JavaScript executes in their browser context. No public exploit has been identified at time of analysis and no CISA KEV listing exists; the CVSS 4.0 score of 2.1 reflects the narrow attack prerequisites and limited subsequent-system impact.

Reflected XSS in Concrete CMS 9.5.0 and below allows a remote unauthenticated attacker to inject and execute arbitrary JavaScript in the browser of an authenticated admin or report viewer who clicks a crafted URL targeting the legacy form reports dashboard. The vulnerable component, Concrete\Core\Legacy\Pagination, raw-interpolates a user-controlled URL value directly into an HTML href attribute, enabling attribute injection per CWE-83. With a CVSS 4.0 score of 6.0 and high confidentiality impact (VC:H) on the vulnerable system, successful exploitation can lead to session token theft; no public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV.

Reflected XSS in Nuxt's `navigateTo()` function allows remote attackers to inject and execute arbitrary JavaScript in the application's origin during server-side rendering. Applications passing user-controlled input to `navigateTo(url, { external: true })` - the common post-login `?next=` or `?redirect=` redirect pattern - are affected across nuxt versions 3.4.3-3.21.5 and 4.0.0-alpha.1-4.4.5. A full proof-of-concept is published in the GitHub Security Advisory GHSA-fx6j-w5w5-h468; no public exploit identified at time of analysis beyond that PoC, and this CVE does not appear in CISA KEV.

Improper input neutralization in Palo Alto Networks PAN-OS management web interface allows authenticated high-privilege administrators to bypass system restrictions and execute arbitrary commands through command injection. The vulnerability affects PAN-OS across multiple versions (specific version ranges not independently confirmed from provided data), with a low EPSS exploitation probability (0.06%, 17th percentile) and no confirmed active exploitation or public proof-of-concept. Risk is significantly reduced when CLI access is restricted to a limited administrator group; Cloud NGFW and Prisma Access are unaffected.
