Title
Invoking "go bug" follows symlinks in predictable temporary filenames in cmd/go
Summary
The "go bug" command writes to two files with predictable names in the system temporary directory (for example, "/tmp"). An attacker with access to the temporary directory can create a symlink in one of these names, causing "go bug" to overwrite the target of the symlink.

Title
Bypass of meta content URL escaping causes XSS in html/template
Summary
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.

Title
ReverseProxy forwards queries with more than urlmaxqueryparams parameters in net/http/httputil
Summary
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.

Title
Malicious module proxy can bypass checksum database in cmd/go
Summary
A malicious module proxy can exploit a flaw in the go command's validation of module checksums to bypass checksum database validation. This vulnerability affects any user using an untrusted module proxy (GOMODPROXY) or checksum database (GOSUMDB). A malicious module proxy can serve altered versions of the Go toolchain. When selecting a different version of the Go toolchain than the currently installed toolchain (due to the GOTOOLCHAIN environment variable, or a go.work or go.mod with a toolchain line), the go command will download and execute a toolchain provided by the module proxy. A malicious module proxy can bypass checksum database validation for this downloaded toolchain. Since this vulnerability affects the security of toolchain downloads, setting GOTOOLCHAIN to a fixed version is not sufficient. You must upgrade your base Go toolchain. The go tool always validates the hash of a toolchain before executing it, so fixed versions will refuse to execute any cached, altered versions of the toolchain. The go tool trusts go.sum files to contain accurate hashes of the current module's dependencies. A malicious proxy exploiting this vulnerability to serve an altered module will have caused an incorrect hash to be recorded in the go.sum. Users who have configured a non-trusted GOPROXY can determine if they have been affected by running "rm go.sum ; go mod tidy ; go mod verify", which will revalidate all dependencies of the current module. The specific flaw in more detail: The go command consults the checksum database to validate downloaded modules, when a module is not listed in the go.sum file. It verifies that the module hash reported by the checksum database matches the hash of the downloaded module. If, however, the checksum database returns a successful response that contains no entry for the module, the go command incorrectly permitted validation to succeed. A module proxy may mirror or proxy the checksum database, in which case the go command will not connect to the checksum database directly. Checksums reported by the checksum database are cryptographically signed, so a malicious proxy cannot alter the reported checksum for a module. However, a proxy which returns an empty checksum response, or a checksum response for an unrelated module, could cause the go command to proceed as if a downloaded module has been validated.

Summary
cert-manager-controller DoS via Specially Crafted DNS Response
Details
Impact
The cert-manager-controller performs DNS lookups during ACME DNS-01 processing (for zone discovery and propagation self-checks). By default, these lookups use standard unencrypted DNS.
An attacker who can intercept and modify DNS traffic from the cert-manager-controller pod can insert a crafted entry into cert-manager's DNS cache. Accessing this entry will trigger a panic, resulting in Denial of Service (DoS) of the cert-manager controller.
The issue can also be exploited if the authoritative DNS server for the domain being validated is controlled by a malicious actor.
Patches
The vulnerability was introduced in cert-manager v1.18.0 and has been patched in cert-manager v1.19.3 and v1.18.5, which are the supported minor releases at the time of publishing.
cert-manager versions prior to v1.18.0 are unaffected.
Workarounds
- Using DNS-over-HTTPS reduces the risk of DNS traffic being intercepted and modified.
- Note that DNS-over-HTTPS does not prevent the risk of an attacker-controlled authoritative DNS server.
Resources
- Fix for cert-manager 1.18: https://github.com/cert-manager/cert-manager/pull/8467
- Fix for cert-manager 1.19: https://github.com/cert-manager/cert-manager/pull/8468
- Fix for master branch: https://github.com/cert-manager/cert-manager/pull/8469

Summary
Helm Chart extraction output directory collapse via `Chart.yaml` name dot-segment
Details
Helm is a package manager for Charts for Kubernetes. In Helm versions <=3.20.1 and <=4.1.3, a specially crafted Chart will cause helm pull --untar [chart URL | repo/chartname] to write the Chart's contents to the immediate output directory (as defaulted to the current working directory; or as given by the --destination and --untardir flags), rather than the expected output directory suffixed by the chart's name.
Impact
The bug enables writing the Chart's contents (unpackaged/untar'ed) to the output directory <output dir>/, instead of the expected <output dir>/<chart name>/, potentially overwriting the contents of the targeted directory.
Note: a chart name containing POSIX dot-dot, or dot-dot and slashes (as if to refer to parent directories) do not resolve beyond the output directory as designed.
Patches
This issue has been resolved in Helm v3.20.2 and v4.1.3
A Chart with an unexpected name (those specified to be "." or ".."), or a Chart name which results in a non-unique directory will be rejected.
Workarounds
Ensure the the name of the Chart does not comprise/contain POSIX pathname special directory references ie. dot-dot ("..") or dot ("."). In addition, ensuring that the pull --untar flag (or equivalent SDK option) refers to a unique/empty output directory prevents chart extraction from inadvertently overwriting existing files within the specified directory.

"details": "Helm is a package manager for Charts for Kubernetes. In Helm versions \u003c=3.20.1 and \u003c=4.1.3, a specially crafted Chart will cause `helm pull --untar [chart URL | repo/chartname]` to write the Chart\u0027s contents to the immediate output directory (as defaulted to the current working directory; or as given by the `--destination` and `--untardir` flags), rather than the expected output directory suffixed by the chart\u0027s name.\n\n### Impact\n\nThe bug enables writing the Chart\u0027s contents (unpackaged/untar\u0027ed) to the output directory `\u003coutput dir\u003e/`, instead of the expected `\u003coutput dir\u003e/\u003cchart name\u003e/`, potentially overwriting the contents of the targeted directory.\n\nNote: a chart name containing POSIX dot-dot, or dot-dot and slashes (as if to refer to parent directories) do not resolve beyond the output directory as designed.\n\n### Patches\n\nThis issue has been resolved in Helm v3.20.2 and v4.1.3\n\nA Chart with an unexpected name (those specified to be \".\" or \"..\"), or a Chart name which results in a non-unique directory will be rejected.\n\n### Workarounds\n\nEnsure the the name of the Chart does not comprise/contain POSIX pathname special directory references ie. dot-dot (\"..\") or dot (\".\"). In addition, ensuring that the `pull --untar` flag (or equivalent SDK option) refers to a unique/empty output directory prevents chart extraction from inadvertently overwriting existing files within the specified directory.\n\n### Credits\n\nOleh Konko\n@1seal",
