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-2026-15754
Medium

Mattermost versions 11.7.x <= 11.7.6, 11.8.x <= 11.8.3 fail to re-validate that each target channel still belongs to the requesting admin's team when calling the policy unassign endpoint. This allows an authenticated team administrator to remove ABAC policy assignments from channels outside their team after a channel has been moved to another team.

CVE-2026-10527
Medium

Mattermost versions 11.7.x <= 11.7.6, 10.11.x <= 10.11.21, 11.8.x <= 11.8.3 fail to reconcile SchemeAdmin flags with a user's current role, which allows a user demoted to System Guest to retain Board Admin privileges and perform admin-only operations via the Boards REST API or UI.

CVE-2026-59911
Medium

Dell ObjectScale versions prior to 4.3.0.1 contain an insertion of sensitive information into log file vulnerability in svc_tools. A low privileged attacker with local access could exploit this to disclose information.

CVE-2026-75010
Medium

Roundcube Webmail before 1.6.18 and 1.7.3 has a vulnerability in the modoboa driver of the password plugin that could leak a Modoboa API authentication token to a user-controlled host via crafted session data. This affects only instances using the password plugin with the modoboa driver.

CVE-2026-75007
Medium

Roundcube Webmail before 1.6.18 and 1.7.3 is vulnerable to LDAP search filter injection via unescaped %u/%fu/%d substitution, which may lead to information disclosure or privilege escalation.

CVE-2026-75006
Medium

Roundcube Webmail before 1.6.18 and 1.7.3 has insufficient CSS sanitization in HTML emails, which may lead to SSRF or information disclosure, e.g., if stylesheet links point to local network hosts. This is due to incomplete fixes for CVE-2026-35540, CVE-2026-48843, and CVE-2026-62643.

CVE-2026-75004
Medium

Roundcube Webmail before 1.6.18 and 1.7.3 has improper rule name quoting that could lead to managesieve_disabled_actions setting bypass via a crafted rule name in a Sieve script. This affects only instances using the managesieve plugin.

CVE-2026-75003
Medium

Roundcube Webmail before 1.6.18 and 1.7.3 has an unclosed url() in a FuncIRI attribute of an SVG image that could evade remote image blocking, potentially leading to information disclosure or privilege escalation.

CVE-2026-75000
Medium

Roundcube Webmail before 1.6.18 and 1.7.3 has improper HTML/CSS sanitization of the SVG animate "by" attribute that may lead to remote image blocking bypass, potentially resulting in information disclosure or privilege escalation.

CVE-2026-74999
Medium

Roundcube Webmail before 1.6.18 and 1.7.3 is vulnerable to stored XSS in the "Add to address book" action.

CVE-2026-40126
Medium

OutSystems Service Center is vulnerable to DOM-based Cross-Site Scripting (XSS) that can be exploited by a low-privileged attacker via uploading a file with a malicious filename containing JavaScript code. The vulnerability exists in all locations where files can be attached and prepared for upload. Fixed in version 11.41.2.

CVE-2026-74890
Medium

openssl_encrypt versions before 1.4.0 contain an authentication bypass vulnerability in CamelliaCipher that disables HMAC tag generation and verification when the PYTEST_CURRENT_TEST environment variable is set. Attackers with code execution can set this environment variable to produce unauthenticated ciphertext and bypass integrity protection on encrypted data.

CVE-2026-74881
Medium

openssl_encrypt versions before 1.4.0 configure CORS with allow_origins set to wildcard and allow_credentials enabled to true. Attackers can create malicious websites that make authenticated cross-origin requests to the API on behalf of any user who visits them.

CVE-2026-74873
Medium

openssl_encrypt versions before 1.4.0 expose passwords passed via the --password CLI argument in process listings accessible to all system users. Attackers can read process arguments through ps aux or /proc/[pid]/cmdline to retrieve plaintext passwords and keystore passwords.

CVE-2026-74871
Medium

openssl_encrypt versions before 1.4.6 contain a key derivation flaw in sequential XOR composition mode where the last stage cancels out during key generation. When configured with a single KDF and no prior hashing stage, attackers can bypass memory-hard key derivation and perform offline password cracking at SHA-256 speed instead of the configured KDF cost.

CVE-2026-74867
Medium

SiYuan versions before 3.7.4 contain a cross-site request forgery vulnerability in the session-cookie authentication branch of CheckAuth() that lacks Origin/Referer validation and sets no explicit SameSite attribute on session cookies. Attackers can craft malicious web pages that perform unauthorized actions on behalf of authenticated users by submitting requests with valid session cookies, relying on browser default SameSite policies rather than server-enforced protections.

CVE-2026-74842
Medium

A vulnerability was found in Kira-Pgr PromptShopMCP up to 5bc0cd17358e19a5415d11a531088170d7b81452. Affected is the function download_image of the file server.py of the component Image-Toolkit-MCP-Server. Performing a manipulation of the argument image_url results in server-side request forgery. The attack may be initiated remotely. The exploit has been made public and could be used. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.

CVE-2026-58561
Medium

Null pointer dereference vulnerability in the image codec module. Successful exploitation may affect availability.

CVE-2026-58560
Medium

Null pointer dereference vulnerability in the image codec module. Successful exploitation may affect availability.

CVE-2026-49308
Medium

Permission control vulnerability in the clipboard module. Successful exploitation may affect service confidentiality.
