CVE-2026-27469 1 Isso-comments 1 Isso 2026-04-17 6.1 Medium
Isso is a lightweight commenting server written in Python and JavaScript. In commits before 0afbfe0691ee237963e8fb0b2ee01c9e55ca2144, there is a stored Cross-Site Scripting (XSS) vulnerability affecting the website and author comment fields. The website field was HTML-escaped using quote=False, which left single and double quotes unescaped. Since the frontend inserts the website value directly into a single-quoted href attribute via string concatenation, a single quote in the URL breaks out of the attribute context, allowing injection of arbitrary event handlers (e.g. onmouseover, onclick). The same escaping is missing entirely from the user-facing comment edit endpoint (PUT /id/) and the moderation edit endpoint (POST /id//edit/). This issue has been patched in commit 0afbfe0691ee237963e8fb0b2ee01c9e55ca2144. To workaround, nabling comment moderation (moderation = enabled = true in isso.cfg) prevents unauthenticated users from publishing comments, raising the bar for exploitation, but it does not fully mitigate the issue since a moderator activating a malicious comment would still expose visitors.
CVE-2026-21443 2 Open-emr, Openemr 2 Openemr, Openemr 2026-04-17 6.1 Medium
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the `xl()` translation function returns unescaped strings. While wrapper functions exist for escaping in different contexts (`xlt()` for HTML, `xla()` for attributes, `xlj()` for JavaScript), there are places in the codebase where `xl()` output is used directly without escaping. If an attacker could insert malicious content into the translation database, these unescaped outputs could lead to XSS. Version 8.0.0 fixes the issue.
CVE-2026-20136 1 Cisco 1 Identity Services Engine Software 2026-04-17 6 Medium
A vulnerability in the CLI of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, local attacker with administrative privileges to perform a command injection attack on the underlying operating system and elevate privileges to root. This vulnerability is due to insufficient validation of user supplied input. An attacker could exploit this vulnerability by providing crafted input to a specific CLI command. A successful exploit could allow the attacker to elevate their privileges to root on the underlying operating system.
CVE-2026-28348 2 Fedora-python, Fedoralovespython 2 Lxml Html Clean, Lxml Html Clean 2026-04-17 6.1 Medium
lxml_html_clean is a project for HTML cleaning functionalities copied from `lxml.html.clean`. Prior to version 0.4.4, the _has_sneaky_javascript() method strips backslashes before checking for dangerous CSS keywords. This causes CSS Unicode escape sequences to bypass the @import and expression() filters, allowing external CSS loading or XSS in older browsers. This issue has been patched in version 0.4.4.
CVE-2026-24439 1 Tenda 2 W30e, W30e Firmware 2026-04-16 6.5 Medium
Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) fail to include the X-Content-Type-Options: nosniff response header on web management interfaces. As a result, browsers that perform MIME sniffing may incorrectly interpret attacker-influenced responses as executable script.
CVE-2026-32986 1 Textpattern 1 Textpattern 2026-04-16 6.1 Medium
Textpattern CMS version 4.9.0 contains a second-order cross-site scripting vulnerability that allows attackers to inject malicious scripts by exploiting improper sanitization of user-supplied input in Atom feed XML elements. Attackers can embed unescaped payloads in parameters such as category that are reflected into Atom fields like and , which execute as JavaScript when feed readers or CMS aggregators consume the feed and insert content into the DOM using unsafe methods.
CVE-2026-28350 2 Fedora-python, Fedoralovespython 2 Lxml Html Clean, Lxml Html Clean 2026-04-16 6.1 Medium
lxml_html_clean is a project for HTML cleaning functionalities copied from `lxml.html.clean`. Prior to version 0.4.4, the <base> tag passes through the default Cleaner configuration. While page_structure=True removes html, head, and title tags, there is no specific handling for <base>, allowing an attacker to inject it and hijack relative links on the page. This issue has been patched in version 0.4.4.
CVE-2026-35208 1 Lichess 1 Lila 2026-04-16 5.4 Medium
lichess.org is the forever free, adless and open source chess server. Any approved streamer can inject arbitrary HTML into /streamer and the homepage “Live streams” widget by placing markup in their Twitch/YouTube stream title. CSP is present and blocks inline script execution, but the issue is still a server-side HTML injection sink. To trigger this, a Lichess account only needs to satisfy the normal streamer requirements and get approved. Per Streamer.canApply, that means an account older than 2 days with at least 15 games, or a verified/titled account. After moderator approval, once the streamer goes live, Lichess pulls the platform title and renders it into the UI as-is. No extra privileges are needed beyond a normal approved streamer profile. This vulnerability is fixed with commit 0d5002696ae705e1888bf77de107c73de57bb1b3.
CVE-2026-0818 1 Mozilla 1 Thunderbird 2026-04-15 4.3 Medium
When a user explicitly requested Thunderbird to decrypt an inline OpenPGP message that was embedded in a text section of an email that was formatted and styled with HTML and CSS, then the decrypted contents were rendered in a context in which the CSS styles from the outer messages were active. If the user had additionally allowed loading of the remote content referenced by the outer email message, and the email was crafted by the sender using a combination of CSS rules and fonts and animations, then it was possible to extract the secret contents of the email. This vulnerability was fixed in Thunderbird 147.0.1 and Thunderbird 140.7.1.

CVE-2025-55903 2026-04-15 8.3 High
A HTML injection vulnerability exists in Perfex CRM v3.3.1. The application fails to sanitize user input in the "Bill To" address field within the estimate module. As a result, arbitrary HTML can be injected and rendered unescaped in client-facing documents.
CVE-2025-46583 1 Zte 1 Mc889a 2026-04-15 5.3 Medium

CVE-2025-40769 1 Siemens 1 Sinec Traffic Analyzer 2026-04-15 7.4 High
A vulnerability has been identified in SINEC Traffic Analyzer (6GK8822-1BG01-0BA0) (All versions < V3.0). The affected application uses a Content Security Policy that allows unsafe script execution methods. This could allow an attacker to execute unauthorized scripts, potentially leading to cross-site scripting attacks.
