South Gloucestershire Council has apologised after the personal information of 625 residents was mistakenly shared online during a public consultation.
The breach occurred in October when a spreadsheet containing names, addresses, phone numbers and email addresses was published on the council’s website for three days. Officials took what they called “very prompt action” to remove the data and reported the incident to the Information Commissioner’s Office (ICO).
A spokesperson for the council issued an “unreserved apology”, adding that the council had carried out an initial assessment which found a “low risk” to those affected. But can a data breach involving hundreds of people’s contact details ever really be considered low risk?
Why “low risk” doesn’t mean no risk
When personal data — even basic information like names and email addresses — is published online, it becomes impossible to control where it goes next.
- Exposure can escalate quickly. Contact details can be scraped, shared or reused in phishing or scam attempts within hours.
- Cumulative risk matters. A single breach may seem minor, but when details are cross-referenced with other leaks, victims can be identified and targeted more precisely.
- Emotional impact counts too. Many people feel shaken or violated after discovering their private information was mishandled, especially by a trusted public body.
In this case, the data was reportedly available for three days — long enough for it to be copied or cached. Even if the ICO later agrees the likelihood of harm is “low”, that assessment doesn’t erase the potential for misuse or distress.
The council has promised to review its procedures and delete sensitive information before publishing consultation documents in future. It has also referred the matter to the ICO, which will decide whether enforcement action is required.
For those affected, the key steps are:
- Stay alert to suspicious emails or calls.
- Change passwords on linked accounts and enable multi-factor authentication where possible.
- Contact the ICO if you’re concerned about how your data was handled.
