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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Roundcube Webmail before 1.6.18 and 1.7.3 is vulnerable to stored XSS in the "Add to address book" action.
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.
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.
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.
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.
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.
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.
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.
Null pointer dereference vulnerability in the image codec module. Successful exploitation may affect availability.
Null pointer dereference vulnerability in the image codec module. Successful exploitation may affect availability.
Permission control vulnerability in the clipboard module. Successful exploitation may affect service confidentiality.
