Title
OpenTelemetry-Go has an incomplete fix for CVE-2026-24051: BSD kenv command not using absolute path enables PATH hijacking
Summary
OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.15.0 to 1.42.0, the fix for CVE-2026-24051 changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms. This vulnerability is fixed in 1.43.0.

Summary
go-git: Credential leak via cross-host redirect in smart HTTP transport
Details
Impact
go-git may leak HTTP authentication credentials when following redirects during smart-HTTP clone and fetch operations.
If a remote repository responds to the initial /info/refs request with a redirect to a different host, go-git updates the session endpoint to the redirected location and reuses the original authentication for subsequent requests. This can result in the credentials (e.g. Authorization headers) being sent to an unintended host.
An attacker controlling or influencing the redirect target can capture these credentials and potentially reuse them to access the victim’s repositories or other resources, depending on the scope of the credential.
Clients using go-git exclusively with trusted remotes (for example, GitHub or GitLab), and over a secure HTTPS connection, are not affected by this issue. The risk arises when interacting with untrusted or misconfigured Git servers, or when using unsecured HTTP connections, which is not recommended. Such configurations also expose clients to a broader class of security risks beyond this issue, including credential interception and tampering of repository data.
Patches
Users should upgrade to v5.18.0, or v6.0.0-alpha.2, in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.
The patched versions add support for configuring followRedirects. In line with upstream behaviour, the default is now initial, while users can opt into FollowRedirects or NoFollowRedirects programmatically.
Credit
Thanks to the 3 separate reports from @celinke97, @N0zoM1z0 and @AyushParkara. Thanks for finding and reporting this issue privately to the go-git project. :bow:

Root Cause
sdk/resource/host_id.go line 42:
if result, err := r.execCommand("kenv", "-q", "smbios.system.uuid"); err == nil {
Compare with the fixed Darwin path at line 58:
result, err := r.execCommand("/usr/sbin/ioreg", "-rd1", "-c", "IOPlatformExpertDevice")
The execCommand helper at sdk/resource/host_id_exec.go uses exec.Command(name, arg...) which searches $PATH when the command name contains no path separator.
Affected platforms (per build tag in host_id_bsd.go:4): DragonFly BSD, FreeBSD, NetBSD, OpenBSD, Solaris.
The kenv path is reached when /etc/hostid does not exist (line 38-40), which is common on FreeBSD systems.
Attack
- Attacker has local access to a system running a Go application that imports
go.opentelemetry.io/otel/sdk - Attacker places a malicious
kenvbinary earlier in$PATH - Application initializes OpenTelemetry resource detection at startup
hostIDReaderBSD.read()callsexec.Command("kenv", ...)which resolves to the malicious binary- Arbitrary code executes in the context of the application
Same attack vector and impact as CVE-2026-24051.
Suggested Fix
Use the absolute path:
if result, err := r.execCommand("/bin/kenv", "-q", "smbios.system.uuid"); err == nil {
On FreeBSD, kenv is located at /bin/kenv.

Summary
Denial of Service due to Panic in AWS SDK for Go v2 SDK EventStream Decoder
Details
CVSSv3.1 Rating: [Medium] CVSSv3.1 Score: [5.9] CVSSv3.1 Vector String: [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H]
Summary and Impact
An issue exists in the the EventStream header decoder in AWS SDK for Go v2 in versions predating 2026-03-23. An actor can send a malformed EventStream response frame containing a crafted header value type byte outside the valid range, which can cause the host process to terminate.
Impacted versions: < 2026-03-23
Patches
This issue has been addressed in versions 2026-03-23 and above. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.
Workarounds
Not Applicable
