# Summary Between 18:33 July 13th and 11:20 July 14th 2023 \(PDT\), inline attachments from a small number of emails were incorrectly attached to an unknown number of emails sent by other accounts. # Impact & Metrics | **Question** | **Answer** | | --- | --- | | What was the impact | Incorrect inline attachments were incorrectly attached to a maximum of 17% of overall emails sent by Sendwithus | | Who was impacted | A subset of Sendwithus users sending emails between July 13th 6:33 pm PDT and July 14th 11:20 am PDT may have been impacted | # Detection & Response | **Question** | **Answer** | | --- | --- | | When was the incident detected | July 14th 2023, 10:21 am PDT | | How was the incident detected | An impacted user reached out to the Sendwithus Customer Support team and the incident was quickly escalated | # Timeline _Times are in Pacific Time_ **Jul 13, 2023** **09:44** A new feature related to sending inline attachments was released **18:33** The first detection of a send using the feature since the change **Jul 14, 2023** **10:21** A user reported some of their recipients were receiving unexpected inline attachments on their emails **10:45** Customer Support notifies on-call engineers and the incident is escalated **11:00** Status page updated **11:10** Resolved the issue by reverting to the previous version of Sendwithus **12:40** Underlying issue identified **13:00** Engineering team began an investigation to determine total user impact **17:00** First emails to personally reach out to impacted users sent # Root Cause Analysis **Problem:** A user has reported that some of their emails contain an unexpected attachment. Why? **Reason:** Recent changes were made to our systems to support sending an arbitrary number of inline attachments. This change introduced a bug which resulted in a variable being reused for subsequent emails sent by the same process. Why? **Reason:** An optional parameter in a function definition had a default reference-type value. The issue was not identified before deploying to production. Why? **Reason:** Our current testing, linting, and code review processes were not sufficient to identify the problem. # What can be improved * Changes are being made to our testing and linting processes to catch this category of bug in our CI pipeline * The transient nature of inline attachments and a lack of thread/process level identification in our archived transaction logs has made it difficult to identify exactly which customers and emails were affected. Due to this only the maximum number of _potential_ impacted emails can be identified * Increased controls to improve cross-tenant isolation of information # Corrective actions * The problematic change was quickly identified and reverted after we became aware of the issue * Changes have since been made to the codebase to reduce the probability of similar issues manifesting elsewhere
