No CVSS score has been assigned to CVE-2025-65944 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-65944?

CVE-2025-65944 affects the following packages: @sentry/node (npm), @sentry/astro (npm), @sentry/aws-serverless (npm), @sentry/bun (npm), @sentry/google-cloud-serverless (npm), @sentry/nestjs (npm), @sentry/nextjs (npm), @sentry/node-core (npm), and 4 more. Ecosystems affected: npm.

How do I fix CVE-2025-65944?

Update @sentry/node to 10.27.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-65944 is resolved across your whole dependency graph.

How do I detect CVE-2025-65944 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @sentry/node, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-65944 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2025-65944?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-65944 can be triaged on real exposure rather than presence alone.

Is CVE-2025-65944 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-65944 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-65944?

CVE-2025-65944 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 28th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-65944?

CVE-2025-65944 is classified as CWE-201 (CWE-201). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2025-65944 published, and has it been updated?

CVE-2025-65944 was published on November 25, 2025 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

In version 10.11.0, a change to how the SDK collects request data in Node.js applications caused certain incoming HTTP headers to be added as trace span attributes. When sendDefaultPii: true was set, a few headers that were previously redacted - including Authorization and Cookie - were unintentionally allowed through.

Sentry’s server-side scrubbing (handled by Sentry's Relay edge proxy) normally serves as a second layer of protection. However, because it relied on the same matching logic as the SDK, it also failed to catch these headers in this case.

Users may be impacted if:

Their Sentry SDK configuration has sendDefaultPii set to true
Their application uses one of the Node.js Sentry SDKs with version from 10.11.0 to 10.26.0 inclusively:

@sentry/astro
@sentry/aws-serverless
@sentry/bun
@sentry/google-cloud-serverless
@sentry/nestjs
@sentry/nextjs
@sentry/node
@sentry/node-core
@sentry/nuxt
@sentry/remix
@sentry/solidstart
@sentry/sveltekit

Users can check if their project was affected, by visiting Explore → Traces and searching for “http.request.header.authorization”, “http.request.header.cookie” or similar. Any potentially sensitive values will be specific to users' applications and configurations.

Patches

The issue has been patched in all Sentry JavaScript SDKs starting from the 10.27.0 version.

Workarounds

Sentry strongly encourage customers to upgrade the SDK to the latest available version, 10.27.0 or later. If it is not possible, consider setting sendDefaultPii: false to avoid unintentionally sending sensitive headers. See here for documentation.
