CVE-2025-25962
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue in Coresmartcontracts Uniswap v.3.0 and fixed in v.4.0 allows a remote attacker to escalate privileges via the _modifyPosition function
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA critical privilege escalation vulnerability exists in the _modifyPosition function of Coresmartcontracts Uniswap v3.0, allowing remote attackers to gain elevated privileges (likely administrative/owner rights). The vulnerability stems from improper access control or validation in the position modification logic, enabling unauthorized users to manipulate liquidity positions or contract state.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify deployed Uniswap contract versionQuery the deployed Uniswap contract for its version identifier, or inspect deployment artifacts/configuration files to determine the installed version of Coresmartcontracts UniswapAffected if The version is 3.0 or earlier, or if version cannot be determined but the contract predates the v4.0 release
-
Locate the _modifyPosition function in deployed codeSearch the deployed contract bytecode or source code for the _modifyPosition function definitionAffected if The _modifyPosition function exists in the deployed contract, indicating a version prior to v4.0
-
Verify access control on _modifyPositionInspect the contract's access control modifiers (e.g., onlyOwner, access control lists) applied to the _modifyPosition function to determine if unprivileged callers can invoke itAffected if The function lacks proper authorization checks or has weak access controls that permit privilege escalation
-
Check for recent contract interactionsReview transaction logs or event records for calls to _modifyPosition that may indicate exploitation attempts or abnormal privilege escalation patternsAffected if Transactions exist that elevated privileges unexpectedly or called _modifyPosition from non-admin addresses
The environment is affected if the deployed Uniswap contract version is 3.0 or earlier and the _modifyPosition function is accessible without proper authorization controls.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedImmediately upgrade to Uniswap v4.0 which contains the fix. Review contract state and token balances for any unauthorized modifications, and consider pausing the affected contract if not yet upgraded.
Uniswap v4.0
- 1. Identify all deployments of Coresmartcontracts Uniswap v3.0 in your environment
- 2. Review the v4.0 release notes and migration documentation
- 3. Test v4.0 in a staging environment to verify functionality
- 4. Plan a deployment window with minimal disruption
- 5. Deploy v4.0 to replace all v3.0 instances
- 6. Verify the _modifyPosition function now has proper privilege controls
- 7. Monitor for any anomalies post-deployment
