Descrição técnica

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability when a message is forwarded as an attachment. The subject of the forwarded message was used verbatim to generate the attachment name, so a received message whose subject contains CRLF sequences could inject arbitrary MIME part headers into the outgoing message. Upstream fixed this in the commit “Fix mail header injection via subject of a message forwarded as attachment”, which collapses whitespace in the generated name.

——0Improper Control of Resource Identifiers ('Resource Injection') vulnerability in Apache OFBiz. An authenticate user with access to sfa component can override the service to use on vcard import and access to other service. This issue affects Apache OFBiz: before 24.09.08.

——10Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability in the Bounce (resend) action. rcube_mime::decode_address_list() did not strip control characters from the decoded display name, so a received message whose From display-name carries CRLF sequences in an encoded word could inject arbitrary headers into the message emitted when the user bounces it. Upstream fixed this in the commit “Fix mail header injection via the From display-name in the Bounce (resend) action”.8d CVE-2026-1147255.0 MÉD

——8Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability. rcmail_sendmail stripped newline characters only from the Subject and Organization headers, leaving other header values taken from request parameters unsanitized, so a remote authenticated attacker could inject arbitrary headers into an outgoing message via the References, In-Reply-To, Message-ID and From parameters. Upstream fixed this in the commit “Fix mail header injection via References/In-Reply-To/Message-ID/From parameters”, which normalizes whitespace in every string header value.8d CVE-2026-1147168.5 ALT

——11Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability. rcmail_sendmail::extract_inline_images() used the media type taken from an inline image data URI without validating it, so a remote authenticated attacker could inject arbitrary MIME part headers into the outgoing message by placing CRLF sequences in that media type. Upstream fixed this in the commit “Fix mail header injection via media type in an inline image data URI”, which validates the media type with rcube_mime::is_mimetype_valid().7d CVE-2026-502188.5 ALT

——8Akamai GPA (Guardicore Platform Agent) client on all platforms before 7.4 improperly validates JWT tokens used for seeding. By convincing a user to interact with a malicious link, an attacker can use a spoofed JWT token to inject arbitrary parameters into the client software, resulting in unauthorized reconfiguration and full compromise of the application's functionality. This attack can also be targeted against an already seeded client if the attacker knows the URL of the IDP that the client used for enrollment.17d
