CVE ID : CVE-2026-27469 Published : Feb. 21, 2026, 8:16 a.m. | 8 hours, 48 minutes ago Description : 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 ID : CVE-2026-27466 Published : Feb. 21, 2026, 8:16 a.m. | 6 hours, 48 minutes ago Description : BigBlueButton is an open-source virtual classroom. In versions 3.0.21 and below, the official documentation for "Server Customization" on Support for ClamAV as presentation file scanner contains instructions that leave a BBB server vulnerable for Denial of Service. The flawed command exposes both ports (3310 and 7357) to the internet. A remote attacker can use this to send complex or large documents to clamd and waste server resources, or shutdown the clamd process. The clamd documentation explicitly warns about exposing this port. Enabling ufw (ubuntu firewall) during install does not help, because Docker routes container traffic through the nat table, which is not managed or restricted by ufw. Rules installed by ufw in the filter table have no effect on docker traffic. In addition, the provided example also mounts /var/bigbluebutton with write permissions into the container, which should not be required. Future vulnerabilities in clamd may allow attackers to manipulate files in that folder. Users are unaffected unless they have opted in to follow the extra instructions from BigBlueButton's documentation. This issue has been fixed in version 3.0.22.

CVE ID : CVE-2026-27467 Published : Feb. 21, 2026, 8:16 a.m. | 8 hours, 48 minutes ago Description : BigBlueButton is an open-source virtual classroom. In versions 3.0.19 and below, when first joining a session with the microphone muted, the client sends audio to the server regardless of mute state. Media is discarded at the server side, so it isn't audible to any participants, but this may allow for malicious server operators to access audio data. The behavior is only incorrect between joining the meeting and the first time the user unmutes. This issue has been fixed in version 3.0.20.

CVE ID : CVE-2026-27464 Published : Feb. 21, 2026, 8:16 a.m. | 6 hours, 48 minutes ago Description : Metabase is an open-source data analytics platform. In versions prior to 0.57.13 and versions 0.58.x through 0.58.6, authenticated users are able to retrieve sensitive information from a Metabase instance, including database access credentials. During testing, it was confirmed that a low-privileged user can extract sensitive information including database credentials, into the email body via template evaluation. This issue has been fixed in versions 0.57.13 and 0.58.7. To workaround this issue, users can disable notifications in their Metabase instance to disallow access to the vulnerable endpoints.

CVE ID : CVE-2026-27479 Published : Feb. 21, 2026, 9:15 a.m. | 9 hours, 49 minutes ago Description : Wallos is an open-source, self-hostable personal subscription tracker. Versions 4.6.0 and below contain a Server-Side Request Forgery (SSRF) vulnerability in the subscription and payment logo/icon upload functionality. The application validates the IP address of the provided URL before making the request, but allows HTTP redirects (CURLOPT_FOLLOWLOCATION = true), enabling an attacker to bypass the IP validation and access internal resources, including cloud instance metadata endpoints. The getLogoFromUrl() function validates the URL by resolving the hostname and checking if the resulting IP is in a private or reserved range using FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE. However, the subsequent cURL request is configured with CURLOPT_FOLLOWLOCATION = true and CURLOPT_MAXREDIRS = 3, which means the request will follow HTTP redirects without re-validating the destination IP. This issue has been fixed in version 4.6.1. Severity: 7.7 | HIGH Visit the link for more details, such as CVSS details, affected products, timeline, and more...

CVE ID : CVE-2026-27458 Published : Feb. 21, 2026, 7:16 a.m. | 5 hours, 48 minutes ago Description : LinkAce is a self-hosted archive to collect website links. Versions 2.4.2 and below have a Stored Cross-site Scripting vulnerability through the Atom feed endpoint for lists (/lists/feed). An authenticated user can inject a CDATA-breaking payload into a list description that escapes the XML CDATA section, injects a native SVG element into the Atom XML document, and executes arbitrary JavaScript directly in the browser when the feed URL is visited. No RSS reader or additional rendering context is required — the browser's native XML parser processes the injected SVG and fires the onload event handler. This vulnerability exists because the lists feed template outputs list descriptions using Blade's raw syntax ({!! !!}) without sanitization inside a CDATA block. The critical detail is that because the output sits inside , an attacker can inject the sequence ]]> to close the CDATA section prematurely, then inject arbitrary XML/SVG elements that the browser parses and executes natively as part of the Atom document. This issue has been fixed in version 2.4.3. Severity: 8.7 | HIGH Visit the link for more details, such as CVSS details, affected products, timeline, and more...

CVE ID : CVE-2026-27206 Published : Feb. 21, 2026, 7:16 a.m. | 5 hours, 48 minutes ago Description : Zumba Json Serializer is a library to serialize PHP variables in JSON format. In versions 3.2.2 and below, the library allows deserialization of PHP objects from JSON using a special @type field. The deserializer instantiates any class specified in the @type field without restriction. When processing untrusted JSON input, this behavior may allow an attacker to instantiate arbitrary classes available in the application. If a vulnerable application passes attacker-controlled JSON into JsonSerializer::unserialize() and contains classes with dangerous magic methods (such as __wakeup() or __destruct()), this may lead to PHP Object Injection and potentially Remote Code Execution (RCE), depending on available gadget chains in the application or its dependencies. This behavior is similar in risk profile to PHP's native unserialize() when used without the allowed_classes restriction. Applications are impacted only if untrusted or attacker-controlled JSON is passed into JsonSerializer::unserialize() and the application or its dependencies contain classes that can be leveraged as a gadget chain. This issue has been fixed in version 3.2.3. If an immediate upgrade isn't feasible, mitigate the vulnerability by never deserializing untrusted JSON with JsonSerializer::unserialize(), validating and sanitizing all JSON input before deserialization, and disabling @type-based object instantiation wherever possible.

CVE ID : CVE-2026-27211 Published : Feb. 21, 2026, 6:17 a.m. | 2 hours, 47 minutes ago Description : Cloud Hypervisor is a Virtual Machine Monitor for Cloud workloads. Versions 34.0 through 50.0 arevulnerable to arbitrary host file exfiltration (constrained by process privileges) when using virtio-block devices backed by raw images. A malicious guest can overwrite its disk header with a crafted QCOW2 structure pointing to a sensitive host path. Upon the next VM boot or disk scan, the image format auto-detection parses this header and serves the host file's contents to the guest. Guest-initiated VM reboots are sufficient to trigger a disk scan and do not cause the Cloud Hypervisor process to exit. Therefore, a single VM can perform this attack without needing interaction from the management stack. Successful exploitation requires the backing image to be either writable by the guest or sourced from an untrusted origin. Deployments utilizing only trusted, read-only images are not affected. This issue has been fixed in version 50.1. To workaround, enable land lock sandboxing and restrict process privileges and access.
