    Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering.

13. CVE-2026-39834 Invoking infinite loop on large channel writes in golang.org/x/crypto/ssh

    Published 2026-05-22

    Critical·CVSS 9.1 EPSS 0.60%

    When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent trunca...

14. CVE-2026-39830 Invoking client can cause server deadlock on unexpected responses in golang.org/x/crypto/ssh

    Published 2026-05-22

    High·CVSS 7.5 EPSS 0.68%

    A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a resource leak per connection. Unsolicited global responses are now...

15. CVE-2026-39835 Invoking server panic during CheckHostKey/Authenticate in golang.org/x/crypto/ssh

    Published 2026-05-22

    High·CVSS 7.5 EPSS 0.50%

    SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.

16. CVE-2026-33814 Infinite loop in HTTP/2 transport when given bad SETTINGS_MAX_FRAME_SIZE in net/http/internal/http2 in golang.org/x/net

    Published 2026-05-07

    Published 2025-12-03

    Medium·CVSS 6.5 EPSS 0.30%

    An excluded subdomain constraint in a certificate chain does not restrict the usage of wildcard SANs in the leaf certificate. For example a constraint that excludes the subdomain test.example.com does not prevent a leaf certificate from claiming the SAN *.example.com.

    Published 2025-11-19

    Medium·CVSS 5.3 EPSS 0.55%

    SSH Agent servers do not validate the size of messages when processing new identity requests, which may cause the program to panic if the message is malformed due to an out of bounds read.
