CVE-2026-935767.5 ALT—
———A flaw was found in Netty netty-codec-smtp. The component does not properly validate Carriage Return (CR) and Line Feed (LF) characters in the SMTP command-name field. A remote attacker, if an application routes untrusted input into this field, can embed CR/LF characters to inject arbitrary SMTP commands. This can lead to SMTP command smuggling, allowing for unauthorized email relay or spoofing of sender/recipient addresses. While the impact is significant, the real-world exploitability is considered lower as applications typically do not place user-controlled data in the command-name field.9hCVE-2026-405308.0 ALT28.4%
——9An improper neutralization of CRLF sequences ('CRLF injection') vulnerability in User API in Synology DiskStation Manager (DSM) before 7.2.1-69057-10, 7.2.2-72806-7 and 7.3.2-86009-2 allows remote authenticated users to read or write arbitrary files and conduct denial-of-service attacks after the system is rebooted.11hCVE-2026-908197.3 ALT32.4%
——10A weakness has been identified in a2aproject a2a-java 1.2.0. The affected element is the function BasePushNotificationSender.dispatchNotification of the file server-common/src/main/java/org/a2aproject/sdk/server/tasks/BasePushNotificationSender.java of the component Authorization Header Construction. This manipulation causes http response splitting. The attack can be initiated remotely. Upgrading to version 1.3.0 is sufficient to fix this issue. Patch name: 247a655043f145f6f8e3853724b6a543eaa02001. You should upgrade the affected component.4dCVE-2026-909379.9 CRÍ18.0%
——5froxlor versions before 2.2.5 fail to validate newline characters in subdomain redirect URLs, allowing authenticated customers to inject arbitrary nginx or Apache configuration directives. Attackers can supply URLs containing literal newlines that are written verbatim into vhost config files during cron rebuild, enabling web server configuration corruption, denial of service, or hijacking of HTTP responses across hosted domains.3dCVE-2026-907676.5 MED16.4%
——5Froxlor before 2.3.12 fails to properly validate multi-line SSH public keys in the SshKeys::add() endpoint, allowing customers to inject arbitrary lines into authorized_keys files. Attackers can inject malicious SSH key entries with option directives to gain persistent unauthorized access that survives key deletion and SSH access revocation.5dCVE-2026-868134.8 MED5.0%
——1The MetForm WordPress plugin before 4.1.9 does not properly neutralize newline characters in user-submitted values that are placed into notification email headers, allowing unauthenticated attackers to inject additional email headers, such as Bcc, into the emails the site sends when a submitted field value is configured to populate a header.8d
