CVE-2026-42245
Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. Prior to versions 0.4.24, 0.5.14, and 0.6.4, Net::IMAP::ResponseReader has quadratic time complexity when reading large responses containing many string literals. A hostile server can send responses which are...
CVE-2026-42245 net-imap: Quadratic complexity when reading response literals
Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. Prior to versions 0.4.24, 0.5.14, and 0.6.4, Net::IMAP::ResponseReader has quadratic time complexity when reading large responses containing many string literals. A hostile server can send responses which are...
CVE-2026-42245
Net::IMAP (Ruby) is affected by a performance vulnerability in Net::IMAP::ResponseReader, where reading large responses with many string literals causes quadratic time complexity. This can be exploited by a hostile server to exhaust the client’s CPU, leading to a denial of service. The issue has ...
CVE-2026-42246 net-imap vulnerable to STARTTLS stripping via invalid response timing
Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. Prior to versions 0.3.10, 0.4.24, 0.5.14, and 0.6.4, a man-in-the-middle attacker can cause Net::IMAPstarttls to return "successfully", without starting TLS. This issue has been patched in versions 0.3.10,...

CVE-2026-42246
Net::IMAP (Ruby) versions before 0.3.10, 0.4.24, 0.5.14, and 0.6.4 are affected by a STARTTLS stripping issue. A man-in-the-middle attacker can cause Net::IMAP#starttls to report a successful TLS upgrade without actually enabling TLS, leaving the socket unencrypted. The vulnerability is mitigated...

Denial Of Service
Net::IMAP is vulnerable to Denial of Service. The vulnerability is due to quadratic time complexity in Net::IMAP::ResponseReader when processing large responses with many string literals, allowing a malicious IMAP server to send crafted responses that exhaust CPU resources and cause a denial of...
Improper Transport Layer Protection
net-imap is vulnerable to Improper Transport Layer Protection. The vulnerability is due to improper validation of the STARTTLS negotiation, where a man-in-the-middle attacker can cause Net::IMAPstarttls to report a successful TLS upgrade without establishing encryption, allowing interception of...
CRLF Injection
Net::IMAP is vulnerable to CRLF Injection. The vulnerability is due to insufficient validation and escaping of raw string arguments passed to several IMAP commands, which allows an attacker to inject CRLF sequences and execute arbitrary IMAP commands by supplying crafted user-controlled input...
CRLF Injection
net-imap is vulnerable to CRLF Injection. The vulnerability is due to improper sanitization of Symbol arguments passed to IMAP commands, which allows an attacker to inject CRLF sequences and execute unintended IMAP commands by supplying crafted input...
