CVE-2026-39823 1 Golang 1 Go 2026-10-26 N/A 6.1 MEDIUM
CVE-2026-27142 fixed a vulnerability in which URLs were not correctly escaped inside of a <meta> tag's <content> attribute. If the URL content were to insert ASCII whitespaces around the '=' rune inside of the <content> attribute, the escaper would fail to similarly escape it, leading to XSS.
CVE-2026-33814 1 Golang 2 Go, Http2 2026-10-26 N/A 7.5 HIGH
When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION frames if it receives a SETTINGS_MAX_FRAME_SIZE with a value of 0.
CVE-2026-39836 1 Golang 1 Go 2026-10-26 N/A 7.5 HIGH
The Dial and LookupPort functions panic on Windows when provided with an input containing a NUL (0).
CVE-2026-39825 1 Golang 1 Go 2026-10-26 N/A 5.3 MEDIUM
ReverseProxy can forward queries containing parameters not visible to Rewrite functions. When used with a Rewrite function, or a Director function which parses query parameters, ReverseProxy sanitizes the forwarded request to remove query parameters which are not parsed by url.ParseQuery. ReverseProxy does not take ParseQuery's limit on the total number of query parameters (controlled by GODEBUG=urlmaxqueryparams=N) into account. This can permit ReverseProxy to forward a request containing a query parameter that is not visible to the Rewrite function. For example, the query "a1=x&a2=x&...&a10000=x&hidden=y" can forward the parameter "hidden=y" while hiding it from the proxy's Rewrite function.
CVE-2026-39826 1 Golang 1 Go 2026-10-26 N/A 6.1 MEDIUM
If a trusted template author were to write a <script> tag containing an empty 'type' attribute or a 'type' attribute with an ASCII whitespace, the execution of the template would incorrectly escape any data passed into the <script> block.
CVE-2026-42499 1 Golang 1 Go 2026-10-26 N/A 7.5 HIGH
Pathological inputs could cause DoS through consumePhrase when parsing an email address according to RFC 5322.
CVE-2026-33811 1 Golang 1 Go 2026-10-26 N/A 7.5 HIGH
When using LookupCNAME with the cgo DNS resolver, a very long CNAME response can trigger a double-free of C memory and a crash.
CVE-2026-39820 1 Golang 1 Go 2026-10-26 N/A 7.5 HIGH
Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive CPU exhaustion and memory allocations.
CVE-2026-42505 1 Golang 1 Go 2026-10-25 N/A 5.3 MEDIUM
Handshakes which used Encrypted Client Hello could be de-anonymized by a passive network observer due to a disclosure of pre-shared key identities in the unencrypted client hello.
CVE-2026-39822 1 Golang 1 Go 2026-10-25 N/A 7.8 HIGH
On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /. For example, 'root.Open("symlink/")' will open "symlink" even when "symlink" is a symbolic link pointing outside of the root.
CVE-2025-61729 1 Golang 1 Go 2026-10-18 N/A 7.5 HIGH
Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption.
CVE-2025-61727 1 Golang 1 Go 2026-10-18 N/A 6.5 MEDIUM
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.
CVE-2022-32189 1 Golang 1 Go 2026-10-08 N/A 7.5 HIGH
A too-short encoded message can cause a panic in Float.GobDecode and Rat GobDecode in math/big in Go before 1.17.13 and 1.18.5, potentially allowing a denial of service.
CVE-2025-58187 1 Golang 1 Go 2026-10-08 N/A 7.5 HIGH
Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains.
CVE-2025-61723 1 Golang 1 Go 2026-10-08 N/A 7.5 HIGH
The processing time for parsing some invalid inputs scales non-linearly with respect to the size of the input. This affects programs which parse untrusted PEM inputs.
CVE-2025-58189 1 Golang 1 Go 2026-10-08 N/A 5.3 MEDIUM
When Conn.Handshake fails during ALPN negotiation the error contains attacker controlled information (the ALPN protocols sent by the client) which is not escaped.
CVE-2025-61724 1 Golang 1 Go 2026-10-08 N/A 5.3 MEDIUM
The Reader.ReadResponse function constructs a response string through repeated string concatenation of lines. When the number of lines in a response is large, this can cause excessive CPU consumption.
CVE-2025-47912 1 Golang 1 Go 2026-10-08 N/A 5.3 MEDIUM
The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: "http://[::1]/". IPv4 addresses and hostnames must not appear within square brackets. Parse did not enforce this requirement.
CVE-2025-58185 1 Golang 1 Go 2026-10-08 N/A 5.3 MEDIUM
Parsing a maliciously crafted DER payload could allocate large amounts of memory, causing memory exhaustion.
CVE-2025-58188 1 Golang 1 Go 2026-10-08 N/A 7.5 HIGH
Validating certificate chains which contain DSA public keys can cause programs to panic, due to a interface cast that assumes they implement the Equal method. This affects programs which validate arbitrary certificate chains.
