Description
This security bulletin contains information about 5 vulnerabilities.
1) Path traversal (CVE-ID: CVE-2026-27606)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences within the Rollup module bundler. A remote attacker can send a specially crafted HTTP request and write arbitrary files on the system, leading to arbitrary code execution.
2) Improper Authorization (CVE-ID: CVE-2026-33186)
CWE-ID: CWE-285 - Improper Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to gain access to bypass authorization.
The vulnerability exists due to authorization bypass resulting from improper input validation of the HTTP/2 `:path` pseudo-header. A remote attacker can send raw HTTP/2 frames with malformed `:path` headers directly to the gRPC server to bypass authorization.
3) Stored cross-site scripting (CVE-ID: CVE-2026-40179)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear
The vulnerability allows a remote user to execute arbitrary script in the victim's browser.
The vulnerability exists due to cross-site scripting in the Prometheus web UI tooltip and metrics explorer components when rendering crafted metric names or label values. A remote user can inject crafted metrics through a compromised scrape target, remote write, or the OTLP receiver endpoint to execute arbitrary script in the victim's browser.
User interaction is required to view the affected metric in the Graph UI, such as hovering over a chart tooltip, opening the Metric Explorer, or hovering over a heatmap cell.
4) Information disclosure (CVE-ID: CVE-2026-42151)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to exposure of sensitive information in the /-/config HTTP API endpoint when serving the Azure AD remote write OAuth configuration. A remote attacker can access the endpoint to disclose sensitive information.
Only deployments using Azure AD remote write with OAuth authentication are affected.
5) Uncontrolled Memory Allocation (CVE-ID: CVE-2026-42154)
CWE-ID: CWE-789 - Uncontrolled Memory Allocation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to memory allocation with excessive size value in the remote read endpoint (/api/v1/read) when processing snappy-compressed request bodies. A remote attacker can send a specially crafted request body to cause a denial of service.
Concurrent exploitation can exhaust available memory and crash the Prometheus process.
