Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2026-84642
High

The values of the mail.allowed_attachment_hostnames advanced config setting were used in a regular expression without escaping. For some possible valid hostnames, this could allow certain unintended hostnames to also match and serve remote attachments. This vulnerability was fixed in Thunderbird 155 and Thunderbird 153.2.

CVE-2026-84641
High

A malicious IMAP server can trigger use-after-free and heap-memory disclosure by sending a crafted ID response. Heap contents can ultimately be persisted to prefs.js. This vulnerability was fixed in Thunderbird 155, Thunderbird 140.15, and Thunderbird 153.2.

CVE-2026-84640
High

A maliciously constructed mail header could lead to a one byte read past the end of a buffer. This vulnerability was fixed in Thunderbird 155, Thunderbird 140.15, and Thunderbird 153.2.

CVE-2026-84375
High

js-yaml is a JavaScript YAML parser and dumper. From 3.0.0 until 3.15.2, 4.3.2, and 5.4.1, maxTotalMergeKeys in lib/js-yaml/loader.js and lib/loader.js does not count empty mapping sources while processing the merge key <<. An attacker can alias a large sequence of empty mappings into many merge targets, causing O(N * K) processing while totalMergeKeys remains unchanged and the configured resource limit is never reached. A relatively small YAML document can therefore cause prolonged CPU consumption in applications that parse untrusted YAML, and merge processing is enabled by default on these release lines. In v3 & v4, merge is enabled by default so the severity score is higher. This issue is fixed in versions 3.15.2, 4.3.2, and 5.4.1.

CVE-2026-84374
High

Laravel Excel from 3.1.8 until 3.1.70 has a vulnerability in src/Files/Disk.php where the Disk::copy() method resolves the caller-controlled $destination (supplied through Excel::store(), $export->store(), or storeExcel()) against the process working directory with realpath() instead of the configured filesystem disk. If the path names an existing writable file, Disk::copy() opens it with fopen() in rb+ mode and uses stream_copy_to_stream(), bypassing Flysystem path confinement and allowing an attacker whose application input controls the export path to overwrite arbitrary existing files with export content. The rb+ behavior creates a non-truncating overwrite and trailing bytes when the new export is shorter, and overwriting an executable PHP file can lead to remote code execution.

CVE-2026-83549
HighActively exploitedEPSS 95%

Post-authentication Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability has been identified in the SMA1000 Appliance Management Console (AMC) which in specific conditions could potentially enable a remote authenticated attacker as administrator to execute arbitrary OS commands, resulting in remote code execution.

CVE-2026-76851
High

A Server-Side Request Forgery (SSRF) vulnerability was identified in GitHub Enterprise Server that allowed remote code execution on the instance. Insufficient network isolation allowed malicious pre-receive hook code to impersonate an internal service and redirect trusted internal requests to a privileged service, leading to elevated code execution. Exploitation required pre-receive hook networking to be enabled and either site administrator privileges or write access to a repository containing a configured pre-receive hook. This vulnerability affected all versions prior to 3.22 and was fixed in versions 3.17.20, 3.18.14, 3.19.11, 3.20.7, and 3.21.5.

CVE-2026-19118
High

A time-of-check time-of-use race condition vulnerability was identified in GitHub Enterprise Server that allowed remote code execution. Exploitation required an authenticated user with write access to a repository and precise timing of concurrent upload requests. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.22 and was fixed in versions 3.17.20, 3.18.14, 3.19.11, 3.20.7, and 3.21.5.

CVE-2026-18730
High

A server-side request forgery (SSRF) vulnerability was identified in GitHub Enterprise Server that allowed an unauthenticated attacker to cause the Manage API to send crafted outbound requests to an attacker-controlled host. The HMAC token authenticated only a timestamp, not the request path or body, so an attacker positioned to intercept the outbound request could capture and replay it against privileged management agent endpoints. High-availability deployments were not affected due to a topology restriction.

CVE-2026-84370
High

SVGO, short for SVG Optimizer, is a Node.js library and command-line application for optimizing SVG files. From version 1.0.0 until versions 2.8.4, 3.3.5, and 4.1.0, the opt-in removeScripts plugin, named removeScriptElement in versions 2 and 3, incompletely filters executable links in plugins/removeScripts.js and lib/svgo/tools.js. The plugin does not recognize namespace-prefixed SVG anchor elements such as svg:a with href or namespaced *:href values, and it does not remove ASCII tab, line-feed, or carriage-return characters before checking URL schemes. Browsers remove those characters before parsing a scheme, allowing an executable link to pass the plugin's check. When an application processes attacker-controlled SVG input and serves the result in an active browser context, a victim who activates the surviving link can execute script in the SVG's origin, expose data, modify content, or perform actions as the victim.

CVE-2026-84366
High

Scrapy is a high-level web crawling and scraping framework for Python. Prior to 2.17.0, in scrapy/core/downloader/handlers/s3.py, Scrapy's S3DownloadHandler converts an S3-scheme bucket and key request into a plaintext HTTP request to the corresponding S3 endpoint unless request.meta["is_secure"] is explicitly enabled, then signs and sends the plaintext request with configured AWS credentials. A network attacker who can observe traffic between Scrapy and S3 can read the bucket and key path, AWS Authorization header, X-Amz-Security-Token when temporary credentials are used, S3 object contents, and S3 response headers. An active man-in-the-middle attacker can also modify the plaintext S3 response body, status code, and headers before Scrapy processes them, causing scraped-data poisoning, poisoned exports, HTTP cache poisoning when caching is enabled, or influence over later crawl targets through forged redirects or attacker-controlled links.

CVE-2026-84361
High

Composer, a dependency manager for PHP, has a vulnerability in versions from 1.0 to 2.2.30 and 2.10.3. A malicious package from a custom repository or an untrusted composer.lock file can set source.type to perforce and source.url to a P4PORT value starting with rsh: or jsh:. When the Perforce p4 client is installed and Composer installs the package from source, p4 executes a local command with the privileges of the user or CI account.

CVE-2026-73782
High

A format string vulnerability exists in the command line interface of AOS-CX that could lead to unauthenticated remote code execution. Successful exploitation allows arbitrary code execution as a privileged user on the underlying operating system.

CVE-2026-73781
High

A stored cross-site scripting (XSS) vulnerability exists in the web-based management interface of AOS-CX, allowing an authenticated remote attacker to attack an administrative user. Successful exploitation enables arbitrary script execution in the victim's browser in the context of the interface.

CVE-2026-73780
High

The web-based management interface of AOS-CX switches exposes some sessions to a lack of Cross-Site Request Forgery (CSRF) protection. This could allow a remote unauthenticated attacker to execute arbitrary input against the interface if the attacker convinces an authenticated user to interact with a specially crafted URL.

CVE-2026-73779
High

Vulnerabilities have been identified in the operating system of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls. Successful exploitation could compromise system integrity and further expose sensitive information.

CVE-2026-73778
High

A vulnerability exists in the Credential Manager component that may allow for unauthorized administrative access. An unauthenticated remote attacker could exploit this vulnerability on a device in its factory-default or post-ZTP state before any administrator has configured credentials by providing a predictable factory-default password. Successful exploitation could result in full administrative control of the affected device during the initial setup process.

CVE-2026-73777
High

Vulnerabilities have been identified in the API endpoint of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls.

CVE-2026-73776
High

A signature verification bypass vulnerability exists in the command line interface of AOS-CX. Successful exploitation could allow an authenticated malicious actor with administrative privileges to execute arbitrary code on the underlying operating system, when certain pre-conditions outside of the attacker's control are met.

CVE-2026-73775
High

Vulnerabilities in the API endpoint of AOS-CX could allow a remote attacker authenticated with low privileges to access sensitive information. A successful exploit allows an attacker to retrieve information which could be used to potentially gain further access to network services supported by AOS-CX.
