# CVE-2025-62878: Local Path Provisioner vulnerable to Path Traversal via parameters.pathPattern

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.6% , percentile 48: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 48% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes github.com/rancher/local-path-provisioner (Go) < 0.0.34, fixed in 0.0.34 . Check your lockfile, including transitive dependencies.

## What it is

A malicious user can manipulate the parameters.pathPattern to create PersistentVolumes in arbitrary locations on the host node, potentially overwriting sensitive files or gaining access to unintended directories.

## Affected packages

- Go `github.com/rancher/local-path-provisioner` < 0.0.34 → fixed: 0.0.34

## Affected products (CVE record)

## Severity

- GitHub CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.60% probability of exploitation activity in the next 30 days; percentile 48.
