CVP approved user being blocked on completely benign, non-security queries in fresh sessions on claude.ai (not Claude Code).

[7H35C4r3Cr0W]

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

CVP approved user is being blocked on completely benign, non-security queries on claude.ai when using Opus 4.7. This is not just a Claude Code issue -- this is happening on claude.ai web and mobile.

Blocked query examples:

• Questions about cats
• How to buy DEF CON tickets
• Other general everyday questions unrelated
  to security

Key details:

• These are fresh conversations with zero prior security context
• No security-related terms in the queries
• CVP approval is confirmed and org ID matches
• This started after the Opus 4.7 rollout on April 16th
• Sonnet 4.6 does not exhibit this behavior -- only Opus 4.7
• Thumbs-down feedback has been submitted repeatedly with no resolution
• False positive escalation form has been submitted with no response

This appears to be an account-level classifier issue, not session context bleed. Fresh sessions with no security content are still getting caught.

Related issues: #50162, #49679

What Should Happen?

CVP approved users should never be blocked on queries that have zero relation to cybersecurity.
Everyday questions about animals, events, travel, or anything non-security should pass through regardless of account classification. The AUP
classifier should evaluate the query itself, not apply a blanket restriction at the account level.

Error Messages/Logs

Steps to Reproduce

Steps to Reproduce:

1. Have an active CVP approval on your account with a confirmed matching org ID

2. Open claude.ai on web or mobile

3. Start a brand new conversation -- no prior messages, no security context whatsoever

4. Select Claude Opus 4.7 as the model

5. Type a completely benign query with zero security relevance, examples used:

• "How do I buy tickets to DEF CON?"
• General questions about cats

6. Submit the message

Expected Result:
Claude responds normally to the benign query

Actual Result:
Query is blocked with an AUP/Usage Policy violation error despite:

• Fresh session with no security context
• Query containing no security-related content
• Account having active CVP approval

Additional Notes:

• Switching to Sonnet 4.6 on the same account
  does NOT reproduce the block -- Opus 4.7 specific
• Reproducible consistently across multiple fresh sessions
• Not a one-off -- happens repeatedly
• Happens on both web and mobile clients
• CVP exemption does not appear to be applied at the classifier level for Opus 4.7 on claude.ai, only seems to partially work via
  API per issue [BUG] Cyber Use Case Exemption Granted and works with Claude Chat but still keep getting FPs from safety system when using Claude Code API access. Approved Cyber Use Case Exemption not fully propagating to API in Claude Code using Opus. #49679

Additional Information

Additional Information:

Environment:

• Platform: claude.ai (web and mobile)
• Model: claude-opus-4-7
• Issue started: April 16, 2026 (Opus 4.7
  launch date)
• Previous model claude-opus-4-6 did not
  exhibit this behavior

CVP Status:

• Active CVP approval confirmed
• Org ID verified and matches approval
• Approval covers dual-use cybersecurity
  activities per CVP terms
• False positive escalation form submitted
  -- no response received
• Multiple thumbs-down reports submitted via claude.ai UI -- no resolution

Observed Classifier Behavior:

• Block occurs at account level, not query level
• Fresh sessions with zero security context reproduce the block consistently
• Queries containing no security terminology are being caught
• Suggests CVP exemption is not being applied to the Opus 4.7 classifier on claude.ai

Impact:

• Cannot use Opus 4.7 for any purpose -- including completely unrelated everyday tasks
• Forced to use Sonnet 4.6 as a workaround which is a degraded experience for complex tasks
• CVP approval is effectively useless on
  Opus 4.7 via claude.ai

Related Issues:

• Opus 4.6/4.7 refuses to do any cybersecurity research #50162 -- CVP too tightly wound, not working for approved users
• [BUG] Cyber Use Case Exemption Granted and works with Claude Chat but still keep getting FPs from safety system when using Claude Code API access. Approved Cyber Use Case Exemption not fully propagating to API in Claude Code using Opus. #49679 -- CVP exemptions not applying correctly via claude.ai
• [BUG] Opus 4.7 safety filter produces false-positive refusals on encoded input #52809 -- Opus 4.7 false positive AUP blocks
• Opus 4.7 flags standard computational structural biology as Usage Policy violation, regression from 4.6 #49751 -- Opus 4.7 flagging legitimate non-security work as AUP violation

This has been labeled invalid but the issue is real and affects claude.ai users, not just Claude Code. The Opus 4.7 AUP classifier is shared infrastructure between both products.

Filing here because there is no equivalent public issue tracker for claude.ai and this repo is the only public channel where Anthropic engineers are reachable.

Related issues filed here on the same classifier problem: #50162,#49679, #52809

This is not invalid -- it is a false positive on a CVP approved account affecting a paying customer on claude.ai.

Hi @7H35C4r3Cr0W

I've also passed the CVP, but continue to be rejected today, I switch to Sonnet 4.6 then it works fine, but Opus 4.7 cannot work totoally.

[0x42424242]

Agree totally. Opus 4.7 has turned into something completely useless for me. Sonnet still works. Super frustrating.

[0xROOTPLS]

CVP actually worked for me, got near-zero AUP problems after submitting two CVP apps broadly covering offensive&defensive tooling and actions.

As of May 20, 2026 - AUP flags every prior chat. Something has either lifted with their CVP allowance, or hardened within their classifier.

Opus 4.7 is once again, not usable for most of my work.

I'm also getting the Cyber block. When a PoC was generated with Sonnet no issues. Within that SAME thread I asked Opus 4.8 to reverify the PoC and got the Cyber block.

[7H35C4r3Cr0W]

Update, the fix I mentioned previously no longer works. The only way to use opus 4.7/4.8 is via Claude code or a temp chat. This should be a p0. If anyone can reach out to anthropic that would be most helpful. This is a longstanding unresolved issue for CVP users.

Fui aceito anteriormente, hoje só consigo usar o sonnet... Alguém conseguiu novamente?

[7H35C4r3Cr0W]

Bumping to continue visibility on this p0

[haruki3hhh]

Same situation still, didn't get any effective response from Claude team.
